Overview
Description
The EL7566 is a high-efficiency full-featured synchronous 6A step-down regulator. This document lists the completed schematic diagram and BOM, as well as the layout. With components on one side of the PCB, the complete converter occupies less than 0.72in2 of space. Please refer to the datasheet for the application of features. This demo board is preset to 1.8V for VO and operates at a 500kHz switching frequency. The measured crossover frequencies are around 50kHz with the compensation values.
