VIPER28HN Description

Short technical summary and product information.

The STMicroelectronics VIPER28HN is a high-voltage converter designed for AC-DC applications. It integrates an 800V avalanche-rugged power MOSFET with PWM current-mode control, suitable for meeting stringent energy-saving standards due to its low consumption and burst mode operation under light load.

 

Key electrical specifications include a power output of 16W, an operating frequency of 115kHz, and a voltage range of 8.5V to 23.5V. The device also features an 80% duty cycle and fault protection including current limiting, over temperature, over voltage, and short circuit.

 

This converter is designed for through-hole mounting and comes in a 7-DIP package. It offers isolated output and operates within a temperature range of -40°C to 150°C (TJ). The VIPER28HN is suitable for auxiliary power supplies in consumer electronics, energy meters, and data concentrators.

 

Additional features include embedded HV startup and sense FET, jittered frequency for reduced EMI, and an adjustable extra power timer (EPT) for overload conditions. The device also incorporates output overvoltage protection and thermal shutdown for enhanced reliability.
