DESCRIPTION
The SP6651A Evaluation Board is designed to help the user evaluate the performance
of the SP6651A for use as a single Li-Ion battery Step-Down DC-DC Converter. The
SP6651A operates from 2.7V to 6.5V input, with the highest efficiency in the range 3.0V
to 4.2V where the Li-Ion battery has the most energy. The SP6651AEU evaluation
board is a complete power supply circuit to provide ease of evaluation for the DC/DC
Converter performance.
