The CL1502 is a step-down constant current driver chip with excellent performance, which can realize high-precision LED constant current drive. The chip works in the inductor current critical continuous mode (TM), and the operating voltage covers 85Vac~265Vac. The chip integrates 500V power devices, and peripheral applications can achieve high-precision constant current without auxiliary winding detection and power supply, which greatly reduces external costs.[…]
