LZC8620
Description
The LZC8620 is a single-power stage, isolated and primary side offline LED lighting regulator which achieves high power factor. The proprietary real-current control method can control the LED current accurately from the primary side information. Support flexible current pensation setting in the appointed temperature with a NTC resistor. It can significantly simplify the LED lighting system design by eliminating the secondary side feedback ponents and the opto-coupler. The LZC8620 integrates active power factor correction and works in Quasi Resonance mode (QRM) in order to reduce the MOSFET switching losses. The external programmable line voltage pensation provides a more precise output current throughout the universal AC input voltage range. The leading-edge blanking circuit on the CS/FB input removes the signal glitch and results in reduced external ponents and system cost. The multi-protection features of LZC8620 greatly enhance the system reliability and safety. The...
