Case 1: 50% Stress, Temperature at 40C. MIL-HDBK-217F Notice2 @Ta=25 C, Full load(Ground, Benign, controlled environment). 2. External with Cout = 1F ceramic//10F tantalum capacitors. 3. External with Cout = 2x150uF 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 = 5. [ 21070 Vo - 0.7525 -5110 ] 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 Cin is 2x150F low-ESR polymer capacitors // 2x47F 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.
