Features

design by eliminating the secondary side Building in hysteresis OTP feedback components and the opto-coupler. VDD over voltage protection The LZC811 integrates active power factor Cycle by cycle current limiting on CS correction and works in Quasi Resonance pin mode (QRM) in order to reduce the Secondary peak current protection MOSFET switching losses. With a building in on CS pin 700V start-up MOSFET, IC can eliminate the Output short to GND protection power loss caused by start-.
