The ALT80800 is a compact, high-efficiency, low EMI LED Driver for automotive lighting applications. It 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. Output current is user-selectable by an external current sense resistor, and output voltage is automatically adjusted to drive various numbers of LEDs in a single string.
