VIPER27LN ST AC-DC Converter | 7-DIP | 800V, 60kHz, 1.5A

Product Overview

The VIPER27LN is a high-voltage power IC from STMicroelectronics, integrating an 800V avalanche-rugged Power MOSFET with a PWM controller in a compact 7-DIP package. It is designed for offline AC-DC converters in applications requiring high efficiency, low standby power, and robust protection. The device operates at a fixed 60kHz switching frequency and delivers up to 1.5A peak current, making it suitable for auxiliary power supplies, smart meters, and industrial control systems.
