Note

1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40ºC.

MIL-HDBK-217F Notice2 @Ta=25 ºC, Full load(Ground, Benign, controlled environment).

2. External with C = 1μF ceramic//10μF tantalum capacitors.

3. External with C = 2×150μF polymer capacitors.

4. Output voltage programmable from 0.75V to 3.3V 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:

Rtrim =

[

Vo – 0.7525

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

terminals that ensuring module stability. The external C is 3×150μF low-ESR polymer capacitors // 2×47μF ceramic capacitors at least.

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.
