VIPER318LDTR, Voltage Converter

The STMicroelectronics VIPER31 device is a high-voltage converter that smartly integrates an 800 V avalanche rugged power MOSFET with PWM current-mode control.. The 800 V breakdown allows extended input voltage range to be applied, as well as to reduce the size of the DRAIN snubber circuit.

800 V avalanche-rugged power MOSFET to cover ultra-wide VAC input range
Embedded HV startup and sense FET
Current mode PWM controller
Embedded E/A with 1.2 V reference
Built-in soft-start for improved system reliability
