ALT80600-1 Datasheet Led Driver

Manufacturer: Allegro MicroSystems

Overview: ALT80600 / ALT80600-1 LED Driver with Pre-Emptive Boost for Ultra-High Dimming Ratio and Low Output.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Datasheet Details

The ALT80600 is a multi-output LED driver for small-size LCD backlighting.

It integrates a current-mode boost converter with internal power switch and four current sinks.

The boost converter can drive up to 44 white LEDs, 11 LED per string, at 120 mA (VF = 3.3 V max).

Automotive AEC-Q100 qualified.
Wide input voltage range of 4.5 to 40 V for start/stop, cold crank, and load dump requirements.
Fully integrated LED current sinks and boost converter with internal power MOSFET.
Operate in Boost or SEPIC mode for flexible output.
Drives up to 11 series white LED in 4 parallel strings, at up to 120 mA per string (VF = 3.3 V max).
Programmable boost switching frequency or sync externally from 1 to 2.3 MHz for AL.
