Off-line converter

18 July 2018 Power Electronics / Power Management

The VIPer11 off-line converter with embedded 800 V avalanche-rugged MOSFET from STMicroelectronics enables equipment makers to design tougher auxiliary power supplies and power adaptors. Its 26 V d.c. drain-start voltage allows an ultra-wide line input voltage range and it enhances flexibility in numerous consumer and industrial applications. The high-voltage converter enables flyback, boost or buck/boost power supplies powered directly from the rectified AC line or other DC sources to generate the desired output voltage using a simple voltage divider. High efficiency is assured across a wide load range, even at 5 V output voltage thanks to the logic-level MOSFET feature, and minimum consumption of 10 mW enables extremely low standby power.
