VIPER22ADIP-E AC-DC Converter | 800 V MOSFET Integrated | DIP-8 | STMicroelectronics

VIPER22ADIP-E

An offline AC-DC converter integrating an 800 V MOSFET, PWM controller, and startup circuitry, supporting quasi-resonant/fixed-frequency operation with primary-side regulation, low standby power, and full protection features, housed in a DIP-8 package for appliance auxiliary supplies, industrial power stages, and flyback adapters.

Product Description

Product Overview

The VIPER22ADIP-E is part of STMicroelectronics’ VIPer22A family, integrating an 800 V MOSFET and PWM controller for universal-input flyback designs. It supports low standby consumption, cycle-by-cycle current limiting, thermal shutdown, and primary-side regulation. With a robust DIP-8 package, it is widely used in 2–15 W AC-DC auxiliary supplies and industrial power systems.

Key Features

Integrated 800 V MOSFET for high-voltage robustness
Supports universal 85–265 VAC mains input
Built-in high-voltage startup circuitry
Operating modes: Quasi-resonant / fixed-frequency PWM
Very low standby power for energy-compliant designs
Cycle-by-cycle current limit, thermal shutdown, UVLO
Low-noise switching and excellent EMI behavior
Package: DIP-8 (DIP-8E), ideal for through-hole PCB assembly

Product Applications

Auxiliary supplies in household appliances (refrigerators, washers, air systems)
Low-power AC-DC for industrial control boards and PLC I/O modules
Smart meters and power-monitoring modules
Compact 2–15 W flyback converters
IoT edge-device power and communication-module front-end supply
Auxiliary rail for adapters and chargers
