Features & Applications
The VIPER12ASTR-E is a Low power offline switched-mode power supply primary switcher. The VIPER12A 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. It has an Operating temperature ranges b/w -40 °C to 150 °C and it is available in a SOIC-8 package.

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
