Abstract: optocoupler IC PC817 VIPer22A circuit diagram VIPER22A EEL22 VIPER22A Application Note VIPER22A not isolated PC817 footprint viper22a 3.3v 5v 12v VIPER12A EQUIVALENT Text: the device, i.e. about 80 mA for a VIPer22A. When the output load is decreased and the regulation , hysteresis based on the VDD thresholds of the VIPer22A. The VIPer22A combines a dedicated current mode PWM controller with a high voltage Power MOSFET on the same silicon chip. Typical applications cover off line power supplies for battery charger adapters, standby power supplies for TV or monitors, auxiliary supplies for motor control, etc. The internal control circuit offers the following benefits: ST Microelectronics catalog First Page, datasheet, datasheet search, data sheet, datasheets, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes, triacs, semiconductors shutdown options. Activating this circuit by applying a positive signal on Pin 10 performs two functions: the PWM latch is immediately set providing the fastest turn−off signal to the outputs; and a 150 A current sink begins to discharge the external soft−start capacitor. If the shutdown command
