High voltage converter

Datasheet - production data

Applications

 Auxiliary SMPS for:

– home appliances

– consumer goods

– industrial

– lighting

Description

The device is a high performance high voltage

converter that combines a 730 V rugged power

MOSFET with PWM control. The device embeds

high voltage startup and current sense circuitry,

which helps reduce the number of components in

a BoM. Frequency jittering spreads the EMI and

allows the use of a smaller filter. The burst mode

feature provides very low input power

Features

 730 V avalanche rugged power MOSFET

 PWM controller

 3.3 V reference voltage

 Frequency jittering

consumption at light loads.

 40 mW no load input power at 230 V

 Short-circuit protection

 Thermal shutdown
