VIPER013XSTR

VIPER013XSTR is an energy saving off-line high voltage converter. This device is a high voltage converter smartly integrating an 800V avalanche rugged power MOSFET with PWM current mode control. The power MOSFET with 800V breakdown voltage allows the 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 as it has very low consumption and operates in pulse frequency modulation 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 a complete application to be designed with the minimum number of components. Typical applications include low power SMPS for home appliances, building and home control, small industrial, consumers, lighting, motion control, low power adapters.
