ALT80802 - Buck-Boost or Buck 2 Amp LED Driver

General Description

The ALT80802 is a high-frequency switching regulator that provides constant output current to drive high-power LEDs.

It integrates a power MOSFET for step-down or inverting buckboost conversion.

Key Features

  • Automotive AEC-Q100 qualified.
  • Supports buck-boost or buck mode operation.
  • Supply voltage from 3.8 to 50 V in buck mode ▫ Handles automotive load dump and cold crank ▫ Also supports buck mode from a pre-boost supply.
  • Supports up to 16 V output in buck-boost mode for 4 WLEDs.
  • 150 mΩ integrated MOSFET switch.
  • Programmable switching frequency up to 2.5 MHz for small solution size and operation above AM band.
  • Designed for low EMC with f.
