VIPER319LDTR ST AC-DC Converter | 16-SO | 800V, 60kHz

Product Overview

The VIPER319LDTR is a high-voltage power switching IC from STMicroelectronics, designed for offline AC-DC converters. It integrates an 800V avalanche-rugged Power MOSFET and a PWM controller in a compact 16-SO package. This device offers a fixed 60 kHz switching frequency with frequency jittering for reduced EMI, making it ideal for low-power applications up to 12 W. The VIPER319LDTR features burst-mode operation at light load to minimize standby power consumption, meeting stringent energy-saving regulations.
