NOTES

1.

Test by minimum input and constant resistive load.

2.

To make sure the module is stable, it is necessary that input external capacitors minimize input ripple voltage of the module.

3.

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 a particular output voltage Vout, use the following equation:

Trim Figure

Trim Table

4.

Referred to –Vin pin

5.

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 from instant at which Von/off=0.3VDC

until Vout=10% of vout(set))

6.

Selecting current share function may cause regulations to not meet listed specifications.

CAUTION: This power module is not internally fused. An input line fused must always be used.

*Due to advances in technology, specifications subject to change without notice.
