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.

With current-mode control and simple external pensation, theALT80802 can achieve fast transient response.

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.
