Overview
The VIPER06HSTR, produced by STMicroelectronics, is an advanced 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. It also incorporates advanced frequency jittering to reduce EMI filter costs and operates in burst mode to meet energy-saving regulations.
