DESCRIPTION
The SP6659 Evaluation Board is designed to help the user evaluate the performance of the SP6659 for use as a single Li-Ion battery Step-Down DC-DC Converter. The SP6659 operates from 2.5V to 5.5V input, with the highest efficiency in the range 3.0V to 4.2V where the Li-Ion battery has the most energy. The SP6659EB evaluation board is a complete power supply circuit to provide ease of evaluation for the DC/DC Converter performance.
