Probe
Input reflected-ripple current is measured with a inductor
Lin (4.7uH) and Cin (220uF, ESR < 1.0Ω at 100 KHz) to
simulate source impedance. Capacitor Cin is to offset
possible battery impedance. Current ripple is measured at
the input terminals of the module and measurement
bandwidth is 0-500 KHz.
Peak-to-Peak Output Noise Measurement
Scope measurement should be made by using a BNC
socket, measurement bandwidth is 0-20 MHz. Position the
load between 50 mm and 75 mm from the DC/DC
Converter. A Cout of 0.47uF ceramic capacitor is placed
between the terminals shown below.

Input Source Impedance
The power module should be connected to a low ac-
impedance input source. Highly inductive source
impedances can affect the stability of the power module.

In applications where power is supplied over long lines
and output loading is high, it may be necessary to use a
capacitor at the input to ensure startup.
Capacitor mounted close to the input of the power
module helps ensure stability of the unit, it is
recommended to use a good quality low Equivalent
Series Resistance (ESR < 1.0Ω at 100 KHz) capacitor of
a 12uF for the 12V input devices, a 4.7uF for the 24V
input devices, and a 2.2uF for the 48V devices.

Design & Feature Considerations
Maximum Capacitive Load
The DIW5000 series has limitation of maximum
connected capacitance at the output. The power
module may be operated in current limiting mode
during start-up, affecting the ramp-up and the startup
time.
Output Ripple Reduction
A good quality low ESR capacitor placed as close as
practicable across the load will give the best ripple and
noise performance.
To reduce output ripple, it is recommended to use
3.3uF capacitors at the output.

Overcurrent Protection
To provide protection in a fault (output overload)
condition, the unit is equipped with internal current
limiting circuitry and can endure current limiting for an
unlimited duration. At the point of current-limit
inception, the unit shifts from voltage control to current
control. The unit operates normally once the output
current is brought back into its specified range.
Over voltage Protection
The output over voltage clamp control is independent of
the primary regulation loop. It monitors the voltage on
the output terminals. The control loop of the clamp has
a higher voltage set point than the primary loop. This
provides a redundant voltage control that reduces the
risk of output over voltage.
Soldering and Cleaning Considerations
Post solder cleaning is usually the final board assembly
process before the board or system undergoes electrical
testing. Inadequate cleaning and/or drying may lower the
reliability of a power module and severely affect the
finished circuit board assembly test. Adequate cleaning
and/or drying is especially important for un-encapsulated
and/or open frame type power modules. For assistance
on appropriate soldering and cleaning procedures,
please contact Delta’s technical support team.
Notes:
1. These power converters require a minimum output load
to maintain specified regulation (please see page 6 for
the suggested minimum load). Operation under no-load
conditions will not damage these modules; however,
they may not meet all specifications listed above.
2. These DC/DC converters should be externally fused at
the front end for protection.
6
THERMAL CONSIDERATIONS
Thermal management is an important part of the
system design. To ensure proper, reliable operation,
sufficient cooling of the power module is needed over
the entire temperature range of the module.
Convection cooling is usually the dominant mode of
heat transfer.
Hence, the choice of equipment to characterize the
thermal performance of the power module is a wind
tunnel.
Thermal Testing Setup
Delta’s DC/DC power modules are characterized in
heated vertical wind tunnels that simulate the thermal
environments encountered in most electronics
equipment. This type of equipment commonly uses
vertically mounted circuit cards in cabinet racks in
which the power modules are mounted.
The following figure shows the wind tunnel
characterization setup. The power module is mounted
on a test PWB and is vertically positioned within the
wind tunnel. The space between the facing PWB and
PWB is constantly kept at 25.4mm (1’’).
Figure 7: Wind tunnel test setup
Thermal Derating
Heat can be removed by increasing airflow over the
module. To enhance system reliability, the power
module should always be operated below the maximum
operating temperature. If the temperature exceeds the
maximum module temperature, reliability of the unit
may be affected.
