AL8891Q Automotive Synchronous Buck LED Driver

Diodes Incorporated AL8891Q Automotive Synchronous Buck LED Driver is an easy-to-use synchronous step-down DC-DC LED driver with a high-side current sense capable of driving up to 2A of constant current from an input voltage ranging from 4.5V to 65V. Optimizing high efficiency, the AL8891Q provides a high switching frequency of up to 2.5MHz, allowing a smaller inductor size and compact form factor solution. The pin arrangement allows a simple, optimum PCB layout. Constant on-time control achieves simple control-loop compensation and cycle-by-cycle current limiting with a fast dynamic response.
