The VIPER22ADIP from STMicroelectronics is a low-power, off-line SMPS primary switcher IC. It combines a current mode PWM controller with a high-voltage Power MOSFET on a single chip, simplifying designs for applications such as battery charger adapters and standby power supplies.
This device features a fixed 60 kHz switching frequency and a wide VDD voltage range of 8V to 38V. It offers integrated fault protection, including current limiting, over-temperature, and over-voltage protection with auto-restart. The VIPER22ADIP is designed for isolated power supplies and supports a flyback topology.
Packaged in an 8-DIP format with through-hole mounting, the VIPER22ADIP is suitable for various power supply designs requiring up to 12W of power. Its operating temperature range is -40°C to 150°C (TC).
Typical applications include offline power supplies for battery charger adapters, standby power supplies for TVs or monitors, and auxiliary supplies for motor control. The internal control circuit supports automatic burst mode in low load conditions and overvoltage protection in hiccup mode.
