VIPER35LD ST Off-Line Converter | 16-SO | 800V, 60kHz, 1.5A

Product Overview

The VIPER35LD is a high-voltage off-line switching regulator from STMicroelectronics, integrating an 800V avalanche-rugged power MOSFET and PWM control in a compact 16-SO package. It is designed for low-power AC-DC converters, offering high efficiency, low standby power, and robust protection features. The device operates at a fixed 60kHz switching frequency and delivers up to 1.5A peak current, making it ideal for auxiliary power supplies, smart meters, and home appliances.
