VIPER22AS Description

Short technical summary and product information.

The STMicroelectronics VIPER22AS is a low-power offline SMPS primary switcher IC. It combines a current mode PWM controller with a high-voltage Power MOSFET on a single chip.

 

This device operates at a fixed 60 kHz switching frequency and supports a wide VDD voltage range from 8V to 38V. It is designed for flyback topologies and offers isolated output.

 

Typical applications include off-line power supplies for battery charger adapters, standby power supplies for TVs or monitors, and auxiliary supplies for motor control. The IC includes overtemperature, overcurrent, and overvoltage protection with auto-restart.

 

Packaged in an 8-SOIC surface-mount package, the VIPER22AS is suitable for various power supply designs requiring compact and efficient solutions.
