VIPER20A-E:Fixed frequency off line converter

All the devices are made using VIPower M0 Technology, combines on the same silicon chip a state-of-the-art PWM circuit together with an optimized, high voltage, Vertical Power MOSFET (700V/ 0.5A).

Typical applications cover offline power supplies with a secondary power capability of 10W in wide range condition and 20W in single range or with doubler configuration. It is compatible from both primary or secondary regulation loop despite using around 50% less components when compared with a discrete solution. Burst mode operation is an additional feature of this device, offering the ability to operate in stand-by mode without extra components.

Key Features

  • Adjustable current limitation
  • Low stand-by current
  • Integrated start-up supply
  • Undervoltage lock-out with hysteresis
  • Adjustable switching frequency up to 200 kHz
  • Soft start and shutdown control
  • Current mode control
  • Internally trimmed zener reference
  • Over-temperature protection
  • Automatic burst mode operation in stand-by condition able to meet “blue angel” norm (<1w total power consumption)
