CXLE86248 Wide Voltage Efficient Boost Constant Current LED Driver | 1.2MHz High Frequency Integration | 1A High Current | Ultra Low Power Consumption

CXLE86248 is an efficient boost constant current LED driver that integrates high-frequency power transistors and Schottky diodes. It supports a wide input voltage range of 2.5V~25V and can accurately drive 1~8 strings of LEDs. The chip adopts a constant switching frequency of 1.2MHz and a built-in frequency compensation circuit, significantly reducing the size and cost of peripheral components and optimizing PCB space utilization. Its 200mV low feedback voltage design significantly reduces the power consumption of external sampling resistors, combined with EN pin TTL switch control and 0%~100% PWM stepless dimming function, designed specifically for ultra-low static current (shutdown current of only 3 μ A) and miniaturized devices, making it an ideal power solution for portable electronic products.
