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
