FEATURES DESCRIPTIONS
Enable On/Off
The module can be turned ON/OFF by remote control
with positive on/off logic to ENABLE pin.
For positive logic module, the On/Off pin is pulled high
with an external pull-up resistor, Rpull-up, (see figure 25)
Positive logic On/Off signal turns the module ON during
logic high and turns the module OFF during logic low. If
the positive On/Off function is not used, connect
ENABLE pin to Vin with Rpull-up. (The module will be On)
Rpull-up of 100kohm is recommended.

Over-Current Protection
To provide protection in an output over load fault
condition, the unit is equipped with internal
over-current protection. When the over-current
protection is triggered, the unit enters hiccup mode.
The units operate normally once the fault condition is
removed.
Over-Temperature Protection
ND40 converter does not have built-in over-temperature
protection. Hence, to ensure proper, reliable operation,
sufficient cooling of the power module is needed over
the entire temperature range of the module. Please refer
page.9 for detail information.
DESIGN CONSIDERATIONS
The ND 40A uses two phase and peak current mode
controlled buck topology. The output can be trimmed in
the range of 0.9Vdc to 5.0Vdc by a resistor between
Trim+ pin and Trim－ pin.
The module can be turned ON/OFF by remote control
with positive on/off logic to ENABLE pin. The converter
DC output is disabled when the signal is driven low
(below 0.44V).
The module can protect itself by entering hiccup mode
against over current, short circuit, over voltage condition.
Safety Considerations
For safety-agency approval the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standards.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the
input must meet SELV requirements. The power
module has extra-low voltage (ELV) outputs when all
inputs are ELV.
The input to these units is to be provided with a
maximum 40A or two paralleled 20A of fast-acting
fuses in the ungrounded lead.

FEATURES DESCRIPTIONS (CON.)
Output Voltage Programming
The output voltage of the ND40 converter can be
programmed to any voltage between 0.9Vdc and 5.0Vdc
by connecting one resistor (shown as Rtrim in Figure 26)
between the TRIM+ and Trim－ pins of the module.
Without this external resistor, the output voltage of the
module is 0.6 Vdc. To calculate the value of the resistor
Rtrim for a particular output voltage Vout, please use the
following equation:

Voltage Margining
Output voltage margining can be implemented in the
ND40 converter by connecting a resistor, R margin-up,
between Trim+ pin and Trim－ pin for margining-up the
output voltage, and by connecting a resistor, Rmargin-down,
between the Trim+ pin and the output pin for
margining-down. Figure 27 shows the circuit
configuration for output voltage margining. If unused,
leave the trim pin unconnected. A calculation tool is
available from the evaluation procedure which computes
the values of Rmargin-up and Rmargin-down for a specific output
voltage and margin percentage.

Test Setup of Output Ripple and Noise, and

The measurement set-up outlined in Figure 28 has been
used for output voltage ripple and noise measurement on
NE40 series converters.
Note: Use a 10μF tantalum and 1μF capacitor. Scope
measurement should be taken by using a BNC
connector. Co,min=300μF ceramic capacitors

THERMAL CONSIDERATION
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 neighboring PWB
and the top of the power module is constantly kept at
6.35mm (0.25’’).
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.
Note: Wind tunnel test setup figure dimensions are in
millimeters and (Inches)
