Overview
The VIPER26HDTR, produced by STMicroelectronics, is a smart high voltage converter that integrates an 800 V avalanche-rugged power MOSFET with PWM current mode control. This device is part of the VIPer plus family and is designed to meet stringent energy-saving standards with very low power consumption and burst mode operation under light load conditions.
The VIPER26HDTR supports the design of flyback, buck, and buck-boost converters with a minimum number of components, thanks to its integrated HV startup, sense-FET, error amplifier, and oscillator with jitter.
