A80603-1 - LED Driver

Download the A80603-1 datasheet PDF. This datasheet also covers the A80603 variant, as both devices belong to the same led driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The A80603 and A80603-1 are multi-output LED drivers that integrate a current-mode boost converter with an internal power switch and four current sinks.

Key Features

  • Automotive AEC-Q100 qualified.
  • Enhanced fault handling for ASIL B system compliance.
  • 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).
  • Boost switching fr.
