Overview
The VIPER06XN, part of the VIPerPlus family from 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 protection. The device is capable of powering itself directly from the rectified mains, eliminating the need for an auxiliary bias winding. It also includes advanced features like frequency jittering to reduce EMI and a soft-start mechanism for safe operation.
