The Diodes Incorporated AL8861Y-13 is a hysteresis-mode DC-DC step-down converter designed for driving LEDs. It features a wide input voltage range of 4.5V to 40V and can deliver an output current of up to 1.5A. The device integrates a power switch and a high-side output current sensing circuit, allowing for external adjustment of the output current via a resistor.
This LED driver supports both Analog and PWM dimming through the VSET pin, enabling brightness control from 5% to 100%. It also includes features such as soft-start, LED short protection, inherent open-circuit LED protection, and overtemperature protection (OTP). The switching frequency can reach up to 1MHz, contributing to high efficiency.
The AL8861Y-13 is available in a SOT-89-5 package, suitable for surface mount applications. Its applications include LED backlighting, lighting, and illuminated signs, making it a versatile component for various LED driving needs.
