The STMicroelectronics high voltage converter smartly integrating an 800 V avalanche-rugged power MOSFET with PWM current mode control. The power MOSFET with 800 V 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 fly back, 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.

Embedded HV startup and sense-FET

Current mode PWM controller

Pulse-skip protection to prevent flux-runaway

Embedded thermal shutdown

Built-in soft-start for improved system reliability
