VIPER26LDTR General Description

The VIPER26 device is a smart high voltage converter that integrates an 800 V avalanche-rugged power MOSFET with PWM current mode control. The power MOSFET with 800 V breakdown voltage allows an extended input voltage range to be applied, as well as the size of the DRAIN snubber circuit to be reduced.This IC meets the most stringent energy-saving standards with very low consumption and burst mode operation under light load.The design of flyback, buck and buck boost converters is supported. The integrated HV startup, sense-FET, error amplifier and oscillator with jitter allow complete application designs with a minimum number of components.Wide range single output demonstration board bas.12 V /1 A SMPS wide range demonstration board ba.5 W, 2-output wide-range buck converter based on.9.4 W, 15 V-5 V-3.3 V, three output isolated fly.Low standby loss front-end with inrush current l.
