AL8891 SYNCHRONOUS BUCK LED DRIVER Description The AL8891 is an easy-to-use synchronous step-down DC-DC LED driver with high-side current sense capable of driving up to 2A of constant current from an input voltage ranging from 4.5V to 65V. The AL8891 provides high switching frequency up to 2.5MHz to optimize high efficiency, allowing a smaller inductor size and compact form factor solution. Pin arrangement allows simple, optimum PCB layout. Constant on time control is employed to achieve simple control-loop compensation and cycle-by-cycle current limiting with fast dynamic response. Features such as fault flag, PWM and analog dimming, internal softstart, and shutdown provide a flexible and easy-to-use platform for a wide range of applications.
