LZC811 - LOZEN TECHNOLOGY

LZC811 PSR & PFC LED Driver Controller

Fly-back topology The LZC811 is a single-power stage, • Real-Current control to meet accurate isolated and primary side offline LED lighting output current regulator which achieves high power factor. • Very less components The proprietary real-current control method • Programmable input AC voltage can control the LED current accurately from compensat.

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-up resistors to Output programmable over voltage provide a high efficiency solution for lighting .
