TEST CONFIGURATIONS
DESIGN CONSIDERATIONS
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
Figure 25: Input reflected-ripple test setup
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.
COPPER STRIP

For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the

Remote On/Off
The DCM provide Vo remote sensing to achieve proper
regulation at the load points and reduce effects of
distribution losses on output line. In the event of an open
remote sense line, the module shall maintain local sense
regulation through an internal resistor. The module shall
correct for a total of 0.5V of loss. The remote sense line
impedance shall be < 10.
The DCM 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 DCM series
power modules.
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 28).
Negative logic On/Off signal turns the module ON during
the logic low and turns the module OFF during the logic
high. When the negative On/Off function is not used, tie
the pin to GND (module will be On).

The output voltage of the DCM can be programmed to
any voltage between 0.6Vdc and 3.3Vdc by connecting
one resistor (shown as Rtrim in Figure 31) 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

Voltage Margining
Table 1 provides Rtrim values required for some common
output voltages, By using a 0.5% tolerance trim resistor,
set point tolerance of ±1.5% can be achieved as specified
in the electrical specification.
Output voltage margining can be implemented in the DCM
modules by connecting a resistor, R margin-up, from the Trim
pin to the ground pin for margining-up the output voltage
and by connecting a resistor, Rmargin-down, from the Trim pin
to the output pin for margining-down. Figure 33 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.

Output Voltage Sequencing
The DCM 12V 12A modules include a sequencing feature,
EZ-SEQUENCE that enables users to implement various
types of output voltage sequencing in their applications.
This is accomplished via an additional sequencing pin.
When not using the sequencing feature, either tie the SEQ
pin to VIN or leave it unconnected.
When an analog voltage is applied to the SEQ pin, the
output voltage tracks this voltage until the output reaches
the set-point voltage. The final value of the SEQ voltage
must be set higher than the set-point voltage of the module.
The output voltage follows the voltage on the SEQ pin on a
one-to-one basis. By connecting multiple modules together,
multiple modules can track their output voltages to the
voltage applied on the SEQ pin.

showing limits where the output voltage can be set for different
input voltages.

This will result in the module sinking current if a pre-bias
voltage is present at the output of the module.
FEATURE DESCRIPTIONS (CON.)
For proper voltage sequencing, first, input voltage is
applied to the module. The On/Off pin of the module is left
unconnected (or tied to GND for negative logic modules or
tied to VIN for positive logic modules) so that the module is
ON by default. After applying input voltage to the module,
a minimum 10msec delay is required before applying
voltage on the SEQ pin. This delay gives the module
enough time to complete its internal power-up soft-start
cycle. During the delay time, the SEQ pin should be held
close to ground (nominally 50mV ± 20 mV). This is
required to keep the internal op-amp out of saturation thus
preventing output overshoot during the start of the
sequencing ramp. By selecting resistor R1 (see Figure. 34)
according to the following equation
24950
R1
Figure 34: Circuit showing connection of the sequencing signal to
Vin 0.05
the SEQ pin.
The voltage at the sequencing pin will be 50mV when the
sequencing signal is at zero.
Simultaneous
After the 10msec delay, an analog voltage is applied to the
SEQ pin and the output voltage of the module will track
this voltage on a one-to-one volt bases until the 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.
Simultaneous tracking (Figure 35) is implemented by
using the TRACK pin. The objective is to minimize the
voltage difference between the power supply outputs
during power up and down.
The simultaneous tracking can be accomplished by
connecting VoPS1 to the TRACK pin of PS2. Please note
the voltage apply to TRACK pin needs to always higher
than the VoPS2 set point voltage.
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.

THERMAL CURVES
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.

Ambient Temperature (℃)
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.
