High Voltage Converters

ST’s high-voltage AC-DC converters combine an advanced pulse width modulation (PWM) controller with a high-voltage power MOSFET in a single package. This makes them ideally suited for offline switch mode power supplies (SMPS) with output power spanning from a few to a few tens of watts. The portfolio offers a wide choice of products so you can find the best fit for the most popular topologies, including quasi-resonant, flyback and buck configurations with either isolated or non-isolated implementations, backed up by an extremely large palette of protection features to make sure that even the most stringent reliability targets are met. External component count is also kept at a minimum to help you get the most out of your design at least cost.

The VIPer® high-voltage converter series is composed of monolithic ICs integrating a PWM controller and a 700 V HV vertical power MOSFET.

The VIPerPlus series features an 800 V avalanche-rugged power MOSFET and leading-edge PWM controller and consumes less than 30 mW (at 265 VAC) in standby. It also comes with the largest choice of protection schemes and supports different topologies.

The Altair series has a built-in 900 V avalanche-rugged power MOSFET and a PWM controller specifically designed for opto-less implementation, thus significantly reducing component count.
