ALT80800 Datasheet (Allegro) - Constant-Current 2.0A PWM Dimmable Synchronous Buck LED Driver

ALT80800, Constant-Current 2.0A PWM Dimmable Synchronous Buck LED Driver

The ALT80800 is a synchronous buck switching regulator that provides constant-current output to drive high-power LEDs.

It integrates both high-side and low-side N-channel DMOS switches for DC-to-DC step-down conversion.

A true average current output is achieved using a cycle-by-cycle, controlled on-
