Description

The device is a high-voltage converter that

smartly integrates an 800 V avalanche rugged

power MOSFET with PWM current-mode control.

The power MOSFET with 800 V breakdown

voltage allows extended input voltage range to be

applied, as well as to reduce the size of the

DRAIN snubber circuit. This IC is capable of

meeting the most stringent energy-saving

standards as it has very low consumption and

operates in pulse frequency modulation under

light load. The zero-power mode (ZPM) feature

enables the IC to work in an idle state, where the

system is totally shutdown. An MCU can be

easily connected to the IC for smart ZPM

management and it can be supplied by the IC

itself during the idle state. 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 a minimum

component count. In flyback non isolated

topology, a negative output voltage is easily set

thanks to the integrated error amplifier with

separate ground.
