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.

FEATURES DESCRIPTIONS
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
begin to operate at an input voltage above the under
For negative logic module, connect an open collector
(NPN) transistor or open drain (N channel) MOSFET
between the On/Off pin and the GND pin (see figure 32).
Negative logic On/Off signal turns the module ON during
the logic high and turns the module OFF during the logic
low. When the negative On/Off function is not used, tie the
pin to GND (module will be On).
For positive logic module, the On/Off pin is pulled high
with an external pull-up 5kΩ resistor (see figure 33).
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, tie the pin to Vin.

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.

Output Voltage Programming
The output voltage of the DCT can be programmed to any
voltage between 0.6Vdc and 3.3Vdc by connecting one
resistor (shown as Rtrim in Figure 35) between the TRIM
and GND 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 Vo, please use the following equation:
 1.2 
Rtrim  
 k
Vo  0.6 
For example, to program the output voltage of the DCT
module to 1.8Vdc, Rtrim is calculated as follows:

voltages of 3.3V and lower, the input voltage must be lower
than the maximum of 5.5V. The Lower Limit curve shows
that for output voltages of 1.8V and higher, the input voltage
needs to be larger than the minimum of 2.4V.

output reaches the set-point voltage. To initiate
simultaneous shutdown of the modules, the SEQ pin
voltage is lowered in a controlled manner. The output
voltage of the modules tracks the voltages below their
set-point voltages on a one-to-one basis. A valid input
voltage must be maintained until the tracking and output
voltages reach ground potential.
When using the EZ-SEQUENCETM feature to control
start-up of the module, pre-bias immunity during startup is
disabled. The pre-bias immunity feature of the module
relies on the module being in the diode-mode during
start-up. When using the EZ-SEQUENCETM feature,
modules goes through an internal set-up time of 10msec,
and will be in synchronous rectification mode when the
voltage at the SEQ pin is applied. This will result in the
module sinking current if a pre-bias voltage is present at
the output of the module.

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.
