Overview
The VIPER100-22-E, produced by STMicroelectronics, is a highly integrated power management IC designed using the VIPower M0 Technology. This device combines a state-of-the-art PWM circuit with an optimized, high voltage, Vertical Power MOSFET (620V or 700V / 3A) on the same silicon chip. It is particularly suited for offline power supplies, offering a secondary power capability of up to 100W in single range or with doubler configuration, and 50W in wide range conditions. The VIPER100-22-E is notable for its reduced component count compared to discrete solutions and its ability to operate in burst mode for stand-by conditions, meeting the “Blue Angel” norm of less than 1W total power consumption.
