VIPerPlus Converters


STMicroelectronics offers truly innovative AC-DC conversion


STMicroelectronics high-voltage converters integrate a PWM controller and a high-voltage power MOSFET (800 V) in a single chip, featuring a robust and compact AC-DC solution.

VIPerPlus offline converters offer 800 V avalanche-rugged power section, as well as numerous features to reduce external components count and ensure efficient AC-DC conversion. They feature extremely-low total power consumption (less than 30 mW at 265 V) from the mains when the system is in standby mode. Constant-current operation with an adjustable set point allows use with all mains voltages in SMPS designs up to 30 W.
