VIPER25LN ST Off-Line Converter | 7-DIP | 800V, 60kHz

Product Overview

The VIPER25LN from STMicroelectronics is a high-voltage off-line switching regulator integrated circuit designed for low-power AC-DC converters. It combines an 800V avalanche-rugged power MOSFET with a PWM controller in a compact 7-DIP package. This device simplifies the design of power supplies for applications requiring up to 20W output power, offering high efficiency, low standby power, and comprehensive protection features.
