Overview
The VIPER100-E, developed by STMicroelectronics using VIPower M0 Technology, is a highly integrated power management IC. It 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. This device is designed for offline power supplies, supporting secondary power capabilities of up to 50W in wide range conditions and 100W in single range or with doubler configuration. It offers significant component reduction compared to discrete solutions and features burst mode operation for low power consumption in stand-by mode, meeting the German 'Blue Angel' Norm of less than 1W total power consumption.
