STMICROELECTRONICS VIPER012LS High Voltage Converter IC
The VIPER012LS is a high-voltage off-line converter IC designed for energy-efficient power supplies and LED lighting. It integrates an 800 V avalanche-rugged MOSFET, current mode PWM control, soft-start, and pulse-skipping capabilities to optimize performance and reduce EMI. Suitable for flyback, buck, and buck-boost converter topologies, it features protections such as overload, line overvoltage, thermal shutdown, and maximum duty cycle limit. Its jittered switching frequency, low no-load consumption, and embedded HV startup make it ideal for low power, building control, and consumer electronics applications, ensuring reliable and efficient operation.
