Overview
The VIPER06XSTR, produced by STMicroelectronics, is an offline converter designed for high-voltage applications. It features an 800 V avalanche rugged power section, a PWM controller, and various protection mechanisms such as user-defined overcurrent limit, open-loop failure protection, and hysteretic thermal shutdown. The device can power itself directly from the rectified mains, eliminating the need for an auxiliary bias winding. Advanced frequency jittering reduces EMI filter costs, and the device operates in burst mode to meet energy-saving regulations.
