A80803 Description
The A80803 is a switch-mode, constant-current DC/DC controller for high-power LED automotive lighting applications. The controller is based on a programmable fixed frequency, peak current mode control architecture and can be configured in multiple different switching topologies to suit different application requirements. Both a low-side and high-side gate driver are included to control the external power MOSFETs.
