Highly efficient high voltage converters – VIPer222 and VIPer122


Today, power supply units require more sophisticated methods for improving performance while energy-saving regulations push for greater efficiency. VIPerPlus series of high-voltage converters addresses this challenge, combining an 730 V avalanche-rugged power section with state-of-the-art PWM circuitry for control, and offering a comprehensive set of features and built-in protections. SMPS designs featuring VIPerPlus converters meet the most demanding energy-saving regulations and more: high reliability, flexibility and reduce the number of BOM components.

VIPer122 and VIPer222

The VIPer122 and VIPer222 are a high performance high voltage converters with built-in 730V power MOSFET and PWM control. Converters are equipped with a high-voltage start-up system and a current detection circuit, thanks to which they allow to reduce the number of elements in the BoM. Frequency jittering spreads the EMI and allows the use of a small filter. The burst mode technique allows to obtain a very low input power consumption at light load.

Main features:

  • 730 V avalanche rugged power MOSFET
  • PWM controller
  • 3,3V/1.2V reference voltage (VIPer122/VIPer222)
  • Frequency jittering
  • 40 mW no load input power at 230 VAC
  • Short-circuit protection
  • Thermal shutdown
