DESIGN CONSIDERATIONS
TEST CONFIGURATIONS
Input Source Impedance
To maintain low noise and ripple at the input voltage, it is
critical to use low ESR capacitors at the input to the
module. A highly inductive source can affect the stability
of the module. An input capacitance must be placed
close to the modules input pins to filter ripple current and
ensure module stability in the presence of inductive
traces that supply the input voltage to the module.

Safety Considerations
Remote On/Off
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.
The DCT series power modules have an On/Off pin for
remote On/Off operation. Both positive and negative
On/Off logic options are available in the DCT series power
modules.
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 6A fuse in the ungrounded lead.
Input Under voltage Lockout
At input voltages below the input under voltage lockout
limit, the module operation is disabled. The module will
For positive logic module, connect an open collector
(NPN) transistor or open drain (N channel) MOSFET
between the On/Off pin and the GND pin (see figure26).
Positive logic On/Off signal turns the module ON during
the logic high and turns the module OFF during the logic
low. When the positive On/Off function is not used, leave
the pin floating or tie to Vin (module will be On).
For negative logic module, the On/Off pin is pulled high
with an external pull-up 5kΩ resistor (see figure 35).
Negative logic On/Off signal turns the module OFF during
logic high and turns the module ON during logic low. If the
negative On/Off function is not used, leave the pin floating

Over-Current Protection
To provide protection in an output over load fault
condition, the unit is equipped with internal over-current

Output Voltage Programming
The output voltage of the DCT can be programmed to any
voltage between 0.59Vdc and 5.5Vdc by connecting one
resistor (shown as Rtrim in Figure 29) between the TRIM
and GND pins of the module. Without this external
resistor, the output voltage of the module is 0.59 Vdc. To
calculate the value of the resistor Rtrim for a particular
output voltage Vo, please use the following equation:

THERMAL CONSIDERATIONS
THERMAL CURVES
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.

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

be affected.
