STMicroelectronics VIPER28LE is an offline switching regulator IC from the VIPer™ plus series, designed for flyback topologies. This 10-SDIP package component operates at a 60kHz switching frequency and offers a high breakdown voltage of 800V. Featuring an integrated 80% duty cycle internal switch, it supports up to 16W of power. Key fault protection mechanisms include current limiting, over-temperature, over-voltage, and short-circuit protection. The device requires an 8.5V to 23.5V supply voltage for operation and initiates startup at 14V. This component is suitable for isolated output configurations and finds application in power supplies for industrial controls, consumer electronics, and home appliances. The operating temperature range for this device is -40°C to 150°C.
