LZC811
PSR & PFC LED Driver Controller
General Description
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
compensation
the primary side information.
It can • Leading Edge Blanking on CS/FB pin
significantly simplify the LED lighting system • Protection Features
design by eliminating the secondary side
Building in hysteresis OTP
feedback components and the opto-coupler.
