DESCRIPTION
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 V
IN
> 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 1.5碌A(chǔ) at V
BATTERY
, 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.
