Product Overview

The VIPER50A-22-E is a Switch Mode Power Supply (SMPS) Primary IC 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. Typical applications cover offline power supplies with a secondary power capability of 25W in wide range condition and 50W in single range or with doubler configuration. It is compatible from both primary and 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. Excellent open loop DC and dynamic line regulation is ensured due to the inherent input voltage feed-forward characteristic of the current mode control. This results in improved line regulation, instantaneous correction to line changes and better stability for the voltage regulation loop.
  • Current mode control
  • Soft-start and shutdown control
  • Internally trimmed Zener reference
  • Undervoltage lock-out with hysteresis
  • Integrated start-up supply
  • Over temperature protection
  • Low stand-by current
  • Adjustable current limitation
  • Automatic burst mode operation in stand-by condition able to meet blue angel norm (<1W)
