The device is a high voltage converter smartly integrating a 1050 V avalanche-rugged power section, with a PWM current-mode control. The 1050 V-BV power MOSFET allows to extend the input voltage range, and reduce the size of the DRAIN snubber circuit. This IC meets the most stringent energy-saving standards as it has very low consumption and operates in burst mode under light load.

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.
