   产品概述 返回TOPJ8j嘉泰姆

     CXLE86164 is a primary side control offline LED lighting controller which can achieve accurate LED current and low system cost for an isolated lighting application in a single stage converter. It significantly simplifies the LED lighting system design by eliminating the secondary side feedback components and the opto-coupler. J8j嘉泰姆

The LED current can be adjusted externally by the sense resistor Rs at CS pin. The extremely low start up current and very low operation current (typical 350uA) reduce the power consumption thus lead to high efficiency and low standby power consumption.  J8j嘉泰姆

CXLE86164 offers comprehensive protection coverage with auto-recovery features including open loop protection, short circuit protection, cycle-by-cycle current limiting, VDD over voltage protection, built-in leading edge blanking, VDD under voltage lockout (UVLO), etc.  CXLE86164 is offered in SOT23-5 packageJ8j嘉泰姆
