1.5A 1.3MHz Synchronous Step Down Converter

Overview

TopologyBuck Converter
Input voltage3.3-5.5 V
Output 11.8 V / 1.5 A
IC revision1.1.0

Description

The XRP6657 Evaluation Board is designed to help the user evaluate the performance of the XRP6657 for use as a single LI-ON battery Step-Down DC-DC converter. The XRP6657 operates from 2.5V to 5.5V input, with the highest efficiency in the range 3.0V to 4.2V where the LI-ON battery has the most energy.The XRP6657 Evaluation Board is a complete power supply circuit to provide ease of evaluation for the DC/DC converter performance.
