VIPER12A-E is a low power offline switched-mode power supply primary switcher with the following features: fixed 60 kHz switching frequency, 9 V to 38 V wide range VDD voltage, current mode control, auxiliary undervoltage lockout with hysteresis, high voltage start-up current source, overtemperature, overcurrent and overvoltage protection with auto-restart.
The VIPER12A-E is a low power offline switched-mode power supply primary switcher that combines a dedicated current mode PWM controller with a high voltage power MOSFET on a single silicon chip. It is designed for applications such as battery charger adapters, standby power supplies for TVs or monitors, and auxiliary supplies for motor control.
