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 27: Input reflected-ripple current 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.
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.
Note: Use a 10μF and 1μF capacitor. Scope measurement
should be made using a BNC connector.
The input to these units is to be provided with a fast acting fuse
with a maximum rating of 30A in the positive input lead.

Voltage Margining
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
Output voltage margining can be implemented in the DCL
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 35 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

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.
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. 37)
