VIPER12AS Description

VIPER12AS is a Primary Switcher with a Low Power Off-Line Switched-Mode Power Supply. On the same silicon chip, the VIPER12AS combines a dedicated current mode PWM controller with a high voltage power MOSFET. The large input voltage range on the VDD pin accommodates fluctuations in auxiliary supply voltage, automated burst mode in low load conditions, and overvoltage protection in HICCUP mode are all features of the internal control circuit. Off-line power supplies for battery charger adapters, standby power supplies for TVs or monitors, and auxiliary supplies for motor control are all common applications.


VIPER12AS 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

  • Typical power capability

– European (195 - 265 Vac) 8 W for SO-8,

13 W for DIP-8

– European (85 - 265 Vac) 5 W for SO-8,

8 W for DIP-8


VIPER12AS Applications

  • battery charger adapters

  • standby power supplies for TV or monitors

  • auxiliary supplies for motor control
