Description
The auxiliary FLYBACK signal ensures discontinuous operation and offers a fixed overvoltage detection level of 7.2 V.By connecting an optocoupler to this pin, the peak current setpoint is adjusted accordingl
Features
- a sampling time of 4.5 ms whereas it is 1.5 ms for the B version. The NCP1377 also features an efficient protective circuitries which, in presence of an overcurrent condition, disables the output pulses and enters a safe burst mode, trying to restart. Once the default has gone, the device auto.
- recovers. Finally an internal 1.0 ms Soft.
- Start eliminates the traditional startup stress. Features.
- Free.
- Running Borderline/Critical Mode Quasi.
- Resonant Operation.
