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.
An LED constant current driver IC is a specialized integrated circuit designed to regulate the current supplied to one or more Light Emitting Diodes (LEDs) in a circuit. LEDs are semiconductor devices that emit light when current flows through them, and they require a constant current to operate efficiently and maintain consistent brightness. LED driver ICs ensure that the LED receives a stable and controlled current, regardless of variations in input voltage or temperature.
