VIPER12ADIP-E AC-DC Converter | 700V MOSFET | Energy-Efficient Switcher

VIPER12ADIP-E

Featuring a 700V integrated MOSFET, the VIPER12ADIP-E is an off-line primary-side switcher for flyback/buck SMPS designs, supporting a 9–38V VDD range, fixed 60kHz switching frequency, ultra-low standby power, and comprehensive protections. With a DIP-8 package, it is ideal for small power chargers, auxiliary power supplies, home appliances, and industrial control systems.

Product Description

Product Overview

The VIPER12ADIP-E is a low-power off-line AC-DC converter from STMicroelectronics, integrating a 700V MOSFET and PWM controller, usable in both flyback and buck topologies. With a fixed 60kHz switching frequency, soft-start, jittering, and auto-restart protection mechanisms, it delivers high efficiency and low standby power. It is widely used in chargers, adapters, standby supplies, home appliance control boards, and industrial auxiliary supplies.
