Description
The QBVE067A0B Barracuda series of dc-dc converters are a new generation of fully regulated DC/DC power modules designed to
support 12.0Vdc intermediate bus applications where multiple low voltages are subsequently generated using point of load (POL)
converters, as well as other application requiring a tightly regulated output voltage. The QBVE067A0B series operate from an input
voltage range of 40 to 60Vdc and provide up to 800W output power with a fully regulated output voltage of 12.0Vdc in an industry
standard, DOSA compliant quarter brick. The converter incorporates digital control, synchronous rectification technology, a fully
regulated control topology, and innovative packaging techniques to achieve efficiency exceeding 96.3% at 12.0Vdc output. This leads to
lower power dissipations such that for many applications a heat sink is not required. Standard features include a heat plate to attach
external heat sinks or contact a cold wall, on/off control, output overcurrent and over voltage protection, over temperature protection,
input under and over voltage lockout.
The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Built-in filtering for
both input and output minimizes the need for external filtering.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of
sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum
safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of
30A in the ungrounded input lead of the power supply (see Safety Considerations section). Based on the information provided in this
Data Sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse
manufacturer’s Data Sheet for further information.

Test Configurations
Note: Measure input reflected-ripple current with a simulated
source inductance (LTEST) of 12 µH. Capacitor CS offsets
possible battery impedance. Measure current as shown above.
Figure 13. Input Reflected Ripple Current Test Setup.
Note: Use a 1.0 µF ceramic capacitor, a 10 µF aluminum or
tantalum capacitor and a 750 polymer capacitor. Scope measurement
should be made using a BNC socket. Position the load between 51 mm
and 76 mm (2 in. and 3 in.) from the module.
Figure 14. Output Ripple and Noise Test Setup.
Note: All measurements are taken at the module terminals. When
socketing, place Kelvin connections at module terminals to avoid
measurement errors due to socket contact resistance.
Figure 15. Output Voltage and Efficiency Test Setup.
Design Considerations
Input Source Impedance
The power module should be connected to a low
ac-impedance source. Highly inductive source impedance can
affect the stability of the power module. For the test
configuration in Figure 11, a 660μF electrolytic capacitor, Cin,
(ESR<0.7 at 100kHz), mounted close to the power module
helps ensure the stability of the unit.
Safety Considerations
For safety-agency approval of the system in which the power
module is used, the power module must be installed in
compliance with the spacing and separation requirements of
the end-use safety agency standard, i.e., UL ANSI/UL* 62368-1
and CAN/CSA+ C22.2 No. 62368-1 Recognized, DIN VDE
0868-1/A11:2017 (EN62368-1:2014/A11:2017).
If the input source is non-SELV (ELV or a hazardous voltage
greater than 60 Vdc and less than or equal to 75Vdc), for the
module’s output to be considered as meeting the
requirements for safety extra-low voltage (SELV) or ES1, all of
the following must be true:
▪ The input source is to be provided with reinforced
insulation from any other hazardous voltages, including
the ac mains.
▪ One VIN pin and one VOUT pin are to be grounded, or both
the input and output pins are to be kept floating.
▪ The input pins of the module are not operator accessible.
▪ Another SELV or ES1 reliability test is conducted on the
whole system (combination of supply source and subject
module), as required by the safety agencies, to verify
that under a single fault, hazardous voltages do not
appear at the module’s output.
Note: Do not ground either of the input pins of the module
without grounding one of the output pins. This may
allow a non-SELV/ES1 voltage to appear between the
output pins and ground.
The power module has safety extra-low voltage (SELV) or ES1
outputs when all inputs are SELV.
For input voltages exceeding 60 Vdc but less than or equal to
75 Vdc, these converters have been evaluated to the
applicable requirements of BASIC INSULATION between
secondary DC MAINS DISTRIBUTION input (classified as TNV-2
in Europe) and unearthed SELV outputs.
The input to these units is to be provided with a maximum
30A fast-acting (or time-delay) fuse in the ungrounded input
lead.

Feature Descriptions
Overcurrent Protection
To provide protection in a fault output overload condition, the
module is equipped with internal current-limiting circuitry and
can endure current limiting continuously. If the overcurrent
condition causes the output voltage to fall greater than 3.0V
from Vo,set, the module will shut down and remain latched off.
The overcurrent latch is reset by either cycling the input
power or by toggling the on/off pin for one second. If the
output overload condition still exists when the module
restarts, it will shut down again. This operation will continue
indefinitely until the overcurrent condition is corrected.
A factory configured auto-restart option (with overcurrent and
overvoltage auto-restart managed as a group) is also available.
An auto-restart feature continually attempts to restore the
operation until fault condition is cleared.
Remote On/Off
The module contains a standard on/off control circuit
reference to the VIN(-) terminal. Two factory configured
remote on/off logic options are available. Positive logic
remote on/off turns the module on during a logic-high voltage
on the ON/OFF pin, and off during a logic low. Negative logic
remote on/off turns the module off during a logic high, and on
during a logic low. Negative logic, device code suffix "1," is the
factory-preferred configuration. The On/Off circuit is powered
from an internal bias supply, derived from the input voltage
terminals. To turn the power module on and off, the user
must supply a switch to control the voltage between the
On/Off terminal and the VIN(-) terminal (Von/off). The switch can
be an open collector or equivalent (see Figure 14). A logic low
is Von/off = -0.3V to 0.8V. The typical Ion/off during a logic low
(Vin=50V, On/Off Terminal=0.3V) is 147µA. The switch should
maintain a logic-low voltage while sinking 200µA. During a
logic high, the maximum Von/off generated by the power
module is 8.2V. The maximum allowable leakage current of
the switch at Von/off = 2.4V is 130µA. If using an external
voltage source, the maximum voltage Von/off on the pin is
14.5V with respect to the VIN(-) terminal.
If not using the remote on/off feature, perform one of the
following to turn the unit on:
For negative logic, short ON/OFF pin to VIN(-).
For positive logic: leave ON/OFF pin open.
Figure 16. Remote On/Off Implementation.
Output Overvoltage Protection
The module contains circuitry to detect and respond to
output overvoltage conditions. If the overvoltage condition
causes the output voltage to rise above the limit in the
Specifications Table, the module will shut down and remain
latched off. The overvoltage latch is reset by either cycling the
input power, or by toggling the on/off pin for one second. If
the output overvoltage condition still exists when the module
restarts, it will shut down again. This operation will continue
indefinitely until the overvoltage condition is corrected.
A factory configured auto-restart option (with overcurrent and
overvoltage auto-restart managed as a group) is also available.
An auto-restart feature continually attempts to restore the
operation until fault condition is cleared.
Overtemperature Protection
These modules feature an overtemperature protection circuit
to safeguard against thermal damage. The circuit shuts down
the module when the maximum device reference
temperature is exceeded. The module will automatically
restart once the reference temperature cools by ~25°C.
Input Under/Over voltage Lockout
At input voltages above or below the input under/over voltage
lockout limits, module operation is disabled. The module will
begin to operate when the input voltage level changes to
within the under and overvoltage lockout limits.
Load Sharing
For higher power requirements, the QBVE067A0B-P module
offers an optional feature for parallel operation (-P Option
code). This feature provides a precise forced output voltage
load regulation droop characteristic. The output set point and
droop slope are factory calibrated to insure optimum
matching of multiple modules’ load regulation characteristics.
To implement load sharing, the following requirements should
be followed:
▪ The VOUT(+) and VOUT(-) pins of all parallel modules must be
connected together. Balance the trace resistance for each
module’s path to the output power planes, to insure best
load sharing and operating temperature balance.
▪ VIN must remain between 40Vdc and 60Vdc for droop sharing
to be functional.
▪ It is permissible to use a common Remote On/Off signal to
start all modules in parallel. However if spurious shutdowns
occur at startup due to very low impedance between module
outputs, the modules should be started sequentially instead,
waiting at least the Turn-On Delay Time + Rise Time before
starting the next module.
▪ These modules contain means to block reverse current flow
upon start-up, when output voltage is present from other
parallel modules, thus eliminating the requirement for
external output ORing devices. Modules with the –P option
may automatically increase the Turn On delay, Tdelay, as
specified in the Feature Specifications Table, if output
voltage is present on the output bus at startup.
▪ Insure that the total load is <50% IO,MAX (for a single module)
until all parallel modules have started (load full start >
module Tdelay time max + Trise time).
▪ If fault tolerance is desired in parallel applications, output
ORing devices should be used to prevent a single module
failure from collapsing the load bus.

Feature Descriptions (continued)
Thermal Considerations
The power modules operate in a variety of thermal
environments and sufficient cooling should be provided to
help ensure reliable operation. Heat-dissipating components
are mounted on the top side of the module, and heat is
removed by conduction, convection and radiation to the
surrounding environment. Thermal considerations include
ambient temperature, airflow, module power dissipation, and
the need for increased reliability.
The output power of the module should not exceed the rated
power for the module as listed in the Ordering Information
table. Furthermore, a reduction in the operating temperature
of the module will result in an increase in reliability.
Proper cooling can be verified by measuring the worst-case air
temperature and speed just upstream of the module, and
measuring or estimating the module output power. For
reliable operation, the output power of the module should not
exceed the rated power for the module or the derated power
for the actual operating conditions as indicated in the derating
curves of Figs. 19-24.
A simpler but less accurate way to ensure reliable operation is
to measure the thermal reference temperature (TH1) at the
position indicated in Figure 17. This temperature should be
limited to 100°C, or a lower value for extremely high
reliability. However this method limits power more than
necessary for some thermal conditions; the Tref limit may be
disregarded if the derating-curve method of the previous
paragraph is used.
Figure 17. Location of the thermal reference temperature
TH1 for base plate module.
Heat Transfer via Convection
The thermal data presented here is based on physical
measurements taken in a wind tunnel, using automated
thermo-couple instrumentation to monitor key component
temperatures: FETs, diodes, control ICs, magnetic cores,
ceramic capacitors, opto-isolators, and module PWB
conductors, while controlling the ambient airflow rate and
temperature. For a given airflow and ambient temperature,
the module output power is increased, until one (or more) of
the components reaches its maximum derated operating
temperature, as defined in IPC-9592B. This procedure is then
repeated for a different airflow or ambient temperature until
a family of module output derating curves is obtained. Please
refer to the Application Note “Thermal Characterization
Process For Open-Frame Board-Mounted Power Modules” for
a detailed discussion of thermal aspects including maximum
device temperatures.
Figure 18. Thermal Test Setup .
Increased airflow over the module enhances the heat transfer
via convection. The thermal derating of figure 17- 22 shows
the maximum output current that can be delivered by each
module in the indicated orientation without exceeding the
maximum TH1 temperature versus local ambient
temperature (TA) for several air flow conditions.

Layout Considerations
The QBVE067A0B power module series are low profile in
order to be used in fine pitch system card architectures. As
such, component clearance between the bottom of the power
module and the mounting board is limited. Avoid placing
copper areas on the outer layer directly underneath the
power module. Also avoid placing via interconnects
underneath the power module.
For additional layout guide-lines, refer to FLT012A0Z Data
Sheet.
Through-Hole Lead-Free Soldering
Information
The RoHS-compliant, Z version, through-hole products use the
SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant
components. The module is designed to be processed through
single or dual wave soldering machines. The pins have a RoHS-
compliant, pure tin finish that is compatible with both Pb and
Pb-free wave soldering processes. A maximum preheat rate of
3C/s is suggested. The wave preheat process should be such
that the temperature of the power module board is kept
below 210C. For Pb solder, the recommended pot
temperature is 260C, while the Pb-free solder pot is 270C
max.
Reflow Lead-Free Soldering Information
The RoHS-compliant through-hole products can be processed
with the following paste-through-hole Pb or Pb-free reflow
process.
Max. sustain temperature :
245C (J-STD-020C Table 4-2: Packaging Thickness>=2.5mm /
Volume > 2000mm3),
Peak temperature over 245C is not suggested due to the
potential reliability risk of components under continuous high-
temperature.
Min. sustain duration above 217C : 90 seconds
Min. sustain duration above 180C : 150 seconds
Max. heat up rate: 3C/sec
Max. cool down rate: 4C/sec
In compliance with JEDEC J-STD-020C spec for 2 times reflow
or heat exposures including rework.
Pb-free Reflow Profile
BMP module will comply with J-STD-020 Rev. D
(Moisture/Reflow Sensitivity Classification for
Nonhermetic Solid State Surface Mount Devices) for both Pb-
free solder profiles and MSL classification
procedures. BMP will comply with JEDEC J-STD-020C
specification for 2 times reflow or heat exposures including
rework. The suggested Pb-free solder paste is Sn/Ag/Cu (SAC).
The recommended linear reflow profile using Sn/Ag/Cu solder
is shown in Figure 23.

MSL Rating
The QBVE067A0B modules have a MSL rating as indicated in
the Device Codes table, last page of this document.
Storage and Handling
The recommended storage environment and handling
procedures for moisture-sensitive surface mount packages is
detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and
Use of Moisture/Reflow Sensitive Surface Mount Devices).
Moisture barrier bags (MBB) with desiccant are required for
MSL ratings of 2 or greater. These sealed packages should not
be broken until time of use. Once the original package is
broken, the floor life of the product at conditions of 30°C and
60% relative humidity varies according to the MSL rating (see
J-STD-060A). The shelf life for dry packed SMT packages will
be a minimum of 12 months from the bag seal date, when
stored at the following conditions: < 40° C, < 90% relative
humidity.
Post Solder Cleaning and Drying
Considerations
Post solder cleaning is usually the final circuit board assembly
process prior to electrical board testing. The result of
inadequate cleaning and drying can affect both the reliability
of a power module and the testability of the finished circuit
board assembly. For guidance on appropriate soldering,
cleaning and drying procedures, refer to GE Board Mounted
Power Modules: Soldering and Cleaning Application Note
(AN04-001).
