Typical Applications

Packaging

The A80800-2 is a compact, high-efficiency, low EMI LED Driver for automotive lighting applications. It is a synchronous buck switching regulator that provides constant-current output to drive high-power LEDs. It integrates both high-side and low-side N-channel DMOS switches for DC-to-DC step-down conversion. Output current is user-selectable by an external current sense resistor, and output voltage is automatically adjusted to robustly drive and dim various numbers of LEDs in a single string.

  • 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
  • Automotive Lighting
  • Hi/Lo Beam and Matrix Headlights
  • Front and Rear Fog Lights
  • Daytime Running Lights
  • Turn/stop Lights
  • Dimmable Interior Lights
  • Other Automotive Lighting Applications
