VIPER37HE ST AC-DC Converter | 10-SDIP | 800V, 60kHz

Product Overview

The VIPER37HE is a high-voltage power IC from STMicroelectronics, integrating an 800V avalanche-rugged Power MOSFET with a PWM controller. It is designed for offline AC-DC converters in applications requiring high efficiency and low standby power. The device operates at a fixed 60kHz switching frequency and includes advanced features such as frequency jittering for EMI reduction, hiccup-mode overcurrent protection, and thermal shutdown. Housed in a compact 10-SDIP package, it simplifies design and reduces BOM count.
