VIPER12A STMicroelectronics SMPS Controller

VIPER12A – STMicroelectronics SMPS Controller

is a highly integrated off-line power conversion IC manufactured by STMicroelectronics. Designed for compact and efficient switch-mode power supplies (SMPS), this device combines a PWM controller and a high-voltage MOSFET in a single package. It supports flyback, buck, and buck-boost topologies for power supplies up to 12W, operating directly from rectified mains without the need for external high-voltage switching devices.

Packaged in an 8-pin DIP, the VIPER12A simplifies board layout and enables cost-effective power supply designs in appliances, LED drivers, industrial controls, and chargers.
