UNISONIC TECHNOLOGIES CO., LTD US3602 Preliminary HIGH PRECISION PSR CONSTANT CURRENT LED DRIVER CMOS IC  DESCRIPTION The UTC US3602 is a primary side control offline LED lighting controller. It operates in inductor current DCM mode and can achieve accurate constant current. The UTC US3602 integrates 600V power MOSFET and simplifies the LED lighting system design by eliminating the secondary side feedback components and the opto-coupler. The loop compensation components are also removed while maintaining stability overall operating conditions. The LED current can be adjusted externally by the sense resistor RCS at CS pin. The UTC US3602 achieves ±3% accuracy of LED current along with excellent line regulation and load regulation.
