VIPer22A – SMPS 20W SMART Primary Switcher IC – DIP-8 – STMicroelectronics

The VIPer22A by STMicroelectronics is a high-performance primary switcher IC engineered for Switched-Mode Power Supplies (SMPS). This monolithic device combines a current-mode PWM controller with a 730V avalanche-rugged Power MOSFET on a single chip, packaged in a standard DIP-8 format. It is ideal for creating compact, efficient, and cost-effective offline AC-DC power converters up to 20W.

An integrated high-voltage startup circuit eliminates the need for external high-power bleed resistors, reducing standby power consumption and saving PCB space. The feedback pin connects directly to an optocoupler, simplifying the regulation loop and minimising component count. Built-in protections and ultra-low standby power consumption help meet global energy efficiency regulations.
