Test by minimum input and constant resistive load.
To make sure the module is stable, input external capacitors is necessary that minimize input ripple voltage of the module.
Output voltage programmable from 0.8V to 5.0V by connecting a single resistor (shown as Trim Table)
between the Trim and GND pins of the module. To calculate the value of the resistor Rtrim for a particular output voltage Vout,
use the following equation:
 1200

Rtrim = 
- 100 Ω
 Vout - 0.80

Selecting current share function that the regulations may not meet listed specification.
Case 1: ON/OFF input is set to logic low (module on) and then input power is applied (delay from instant at which Vin=Vin(min.) until Vout=10%
of Vout(set))
Case 2:Input power is applied for at least one second and then the ON/OFF input is set to logic low (delay form instant at which Von/off=0.3VDC
until Vout=10% of Vout(set))
CAUTION: This power module is not internally fused. An input line fuse must always be used.
