Automotive-Grade, Constant-Current 2.0 A PWM Dimmable Synchronous Buck LED Driver

A80800

The A80800-2 is a second-generation to the popular ALT80800, Automotive-Grade, 2A PWM Dimmable Synchronous Buck LED Driver.  The A80800-2 builds on the flexible application features of the ALT80800 with increased diagnostic and recovery features, for robust performance in a wider application space.  The A80800-2 is pin for pin compatible with the ALT80800.

Product Details

Top Features

  • 55Vin rating – Can be used on traditional 12-V automotive, and 24-V trucks, and systems using a pre-boost supply followed by the A80800-2 to drive a high number of LEDs
  • Integrated FETs – No need for external FET(s) or Diode as part of the buck conversion, and higher efficiency
  • Switching frequency dithering for EMI reduction – pass OEM requirements and minimize associated components
  • 5V Vcc can be used to source up to 14mA as a local rail (e.g., power a small uC) – potentially eliminate an LDO
