VIPer1X and VIPer2x Converters

 

STMicroelectronics and Digi-Key introduce the new VIPerPlus smart off-line converters


VIPerPlus smart off-line converters from STMicroelectronics feature a rugged 800V power section, PWM control, and protection circuitry. Soft start and safe auto restart after fault detection removal are inherent. The VIPER16/17/27/28 offer fixed frequency operation at 60kHz or 115kHz, while the VIPER15/25 have Quasi-resonant control. Extremely low standby power consumption allows the VIPerPlus family to meet regulatory energy savings standards. With maximum RDS(on) of 24 ohms, the VIPer family is capable of delivering 5W of output power in adapter application and 7W in open frame configuration from universal 85VAC to 265VAC Line.

Overview

ST’s VIPerPlus series of high-voltage converters combine the innovative avalanche-rugged SuperMESH(TM) power MOSFET with state-of-the-art PWM circuitry. The result is truly innovative AC-DC conversion that is efficient, simpler, quicker and - with component count halved - less expensive.

In addition to benefits such as optimized current-mode control and comprehensive built-in protection circuits, the VIPerPlus family represents the easiest solution to comply with the Blue Angel and Energy Star eco norms, with extremely low total power consumption from the mains when the system is in standby mode.




Features

  • 800V avalanche rugged power MOSFET
  • Standby power less than 50mw @ 265VAC
  • Double level over current protection with auto restart
  • Frequency modulation for low EMI noise
  • Adjustable and accurate over-voltage protection
  • Low standby power consumption
  • Current mode control for simple loop compensation
  • Selectable frequency range
  • Hysteretic thermal shutdown integrated in power section



Applications

  • Home appliances (washing machines, dishwashers, dryers, ovens, refridgerators)
  • Smaller home appliances (coffee makers, food processors, microwave ovens)
  • Adapters/chargers (mobile/smart phones, cordless appliances, shavers, toys, digital cameras, MP3/ portable audio)
  • LED driver (architectural lighting, interior decorating lighting, emergency lights)
