The AL8861QMP-13 from Diodes Incorporated is a hysteresis mode DC-DC step-down LED driver designed for efficient operation. It supports a wide input voltage range from 4.5V to 40V and can deliver an externally adjustable output current up to 1.5A. This device integrates a power switch and a high-side output current sensing circuit, allowing for precise current control via an external resistor.
Key features include high efficiency exceeding 95%, typical 5% output current accuracy, and integrated protection mechanisms such as LED short-circuit, inherent open-circuit LED, sense resistor short-circuit, and overtemperature shutdown. Dimming is achievable through DC voltage or PWM signals applied to the VSET pin, which also controls the on/off state and soft-start time.
Packaged in an 8-MSOP-EP with an exposed pad, the AL8861QMP-13 is suitable for surface mount applications. Its automotive-grade qualification (AEC-Q100 Grade 1) and PPAP capability make it ideal for demanding automotive interior and exterior LED lighting systems. The device operates within a temperature range of -40°C to 85°C (TA) and features a switching frequency up to 1MHz.
