VIPer0P Zero-power off-line high voltage converter

1 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-.

Features

• Smart stand-by architecture using the zero-power mode (ZPM)
• ZPM management by MCU easily realizable
• 800 V avalanche-rugged power MOSFET allowing ultra wide VAC input range to be covered
