Output voltage programmable from 0.7525V to 5V by connecting a single resistor (shown as Rtrim in Table 1) between the TRIM and GND pins of the

module.To calculate the value of the resistor Rtrim for a particular output voltage Vo, use the following equation:

5.

It’s necessary to equip the external input capacitors at the input of the module. The capacitors should connect as close as possible to the input

6.

Device code with suffix “-P” – Positive logic(On/Off is open collector/drain logic input; Signal referenced to GND )

Device code with no suffix – Negative logic (On/Off pin is open collector/drain logic input with external pull –up resistor; signal referenced to GND)

7.

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 Vo=10% of Vo(set))

8.

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=0.3V until

Vo=10% of Vo(set))

CAUTION

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