The AL8861 is a hysteresis mode DC-DC step-down converter designed for driving single or multiple series connected LEDs efficiently. It operates with an input voltage range of 4.5V to 40V and can provide an adjustable output current of up to 1.5A, depending on the package type. The device integrates a power switch and a high-side output current sensing circuit, allowing for precise control of the output current through an external resistor. Dimming capabilities are supported via an external control signal applied to the VSET pin, which can accept either a DC voltage or a PWM signal. The device features a soft-start function, LED short protection, open-circuit LED protection, and over-temperature protection, ensuring reliable operation. With a high efficiency of up to 97% and a maximum switching frequency of 1MHz, the AL8861 is suitable for various applications, including LED retrofitting, low voltage industrial lighting, and illuminated signs. The product is fully RoHS compliant and available in lead-free packages.
