The VIPER26 device is a smart high-voltage converter that integrates an 800V 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.
