VIPER28HD Description

Short technical summary and product information.

The VIPER28HD is a high-voltage offline flyback switch from STMicroelectronics designed for AC-DC power conversion. It integrates an 800V avalanche-rugged power MOSFET and a PWM controller in a compact 16-SOIC surface-mount package. With a rated output power of 16W, it supports an input voltage range of 8.5V to 23.5V and operates at either 60 kHz (L type) or 115 kHz (H type) switching frequency.

 

The device includes comprehensive fault protections: current limiting, over temperature, over voltage, and short circuit protection. An output overvoltage protection with tight tolerance and digital noise filter enhances system reliability. The extra power timer (EPT) blanks overload current for several seconds during startup or transient conditions. Thermal shutdown with hysteresis further increases IC lifetime and system robustness.

 

Packaging options include tube and tape and reel, suitable for automated assembly. The operating junction temperature range is -40°C to 150°C, making it suitable for industrial and consumer applications. The flyback topology with output isolation allows for safe and efficient power supply designs.
