The SP6642/3 Evaluation Board is designed to help the user evaluate the performance of the SP6642/3 for use as a single cell battery input to 2V to 5V output DC-DC Converter. The SP6642/3 starts up from VIN > 0.75V and when started accepts input voltages much less than +0.75V to as high as +1.65V and produces a regulated +3.3V output at up to 20mA. With very low quiescent current of 1.5A at VBATTERY, and up to 85% power efficiency, the SP6642/3 provides maximum battery life for portable applications. The evaluation board is a completely assembled and tested surface mount board which provides easy probe access points to all SP6642/3 Inputs and Outputs so that the user can quickly connect and measure electrical characteristics and waveforms.
