Description
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).
Features
- 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.
