Abstract

We present the development of a LED (Light Emitting Diode) driver based on the synchronous buck power converter. The selected driver's prototype was realized using a FPGA (Field Programmable Gate Array) module as the switching controller, wherein the implementation using Xilinx Vivado 2014.4 and the measurements were successfully performed. The synchronous buck converter topology was investigated to achieve an optimal converter which showed a relatively high gain efficiency of 89% up to 92%.
