DESCRIPTION
The SP4446 Evaluation Boards are designed to help the user evaluate the performance of the
SP4446 for use as a single or dual cell input to +5V output DC-DC Converter. The SP4446
have a fixed output voltage programmed to +5V (consult the factory for other voltage options).
The evaluation board is a completely assembled and tested surface mount board which
provides easy probe access points to all SP4446 Inputs and Outputs so that the user can
quickly connect and measure electrical characteristics and waveforms.
