Beschreibung

The NCV78825R1DAGEVB is a form factor Reference Design of High Efficiency Dual Channel / 2 x 3 A Synchronous Buck LED Driver with Integrated High Side Switch and Current Sensing for Automotive Front Lighting. The reference design can be interfaced via I/O pins and the SPI bus to an external microcontroller. It can be combined with Multiphase Boost Controller daughter boards and create evaluation kit which provides a complete solution turning SPI commands into LED string control. Note: This board is part of the NCV78825R1GEVK LED Driver Evaluation Kit.
