VIPER122 High voltage converter Datasheet - production data Applications  Auxiliary SMPS for: – home appliances – consumer goods – industrial – lighting Features  730 V avalanche rugged power MOSFET  PWM controller  3.3 V reference voltage  Frequency jittering  40 mW no load input power at 230 VAC  Short-circuit protection  Thermal shutdown 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 consumption at light loads. Figure 1.
