DESCRIPTION
The SP6648 Evaluation Board is designed to help the user evaluate the performance of the
SP6648 for use as a single or dual cell input to +3.3V output DC-DC Converter. The output of
the SP6648 is preset to +3.3V or can be adjusted from +2V to +5.5V by manipulating two
external resistors. The evaluation board is a completely assembled and tested surface mount
board which provides easy probe access points to all SP6648 Inputs and Outputs so that the
user can quickly connect and measure electrical characteristics and waveforms.
