Overview
The VIPER265KDTR is a high voltage converter produced by STMicroelectronics. It integrates a 1050 V avalanche-rugged power MOSFET, enabling an ultra-wide VAC input range and reducing the size of the DRAIN snubber circuit. This device features a PWM current mode control and is designed to meet stringent energy-saving standards with very low consumption and burst mode operation under light load. The VIPER265KDTR includes integrated HV startup, sense-FET, error amplifier, and oscillator with jitter, allowing for a complete application design with minimal components.
