5 V / 0.36 A buck converter using VIPerPlus ? VIPer11

The STEVAL-ISA95V1 evaluation board implements a wide range mains buck converter (5 V / 0.36 A) developed for general purpose applications.

The design is built around the VIPer11 off-line high voltage converter from the VIPerPlus family, which intelligently integrates an 800 V rugged power MOSFET with a current-mode control PWM.

The main characteristics of the evaluation board are its single layer, small size and minimal BoM, high efficiency and low standby consumption.

  • Universal AC main input voltage range: 85 VAC to 265 VAC
  • Output range: 5 V / 0.36 A
  • Rated output power: 1.8 W
  • Input power in standby at 230 VAC: less than 18 mW
  • Active mode efficiency: > 65%
  • EMI: according to EN55022-Class-B
  • RoHS compliant
