SP6650 Evaluation
Board Manual
The
SP6650 Evaluation Board
is designed to help the user evaluate the performance of the
SP6650 for use as a single Li-Ion battery input to +5V output DC-DC Converter. The SP6650
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 SP6650UEB evaluation board is a complete power
supply circuit to provide ease of evaluation for the DC/DC Converter performance.
The evaluation board is a completely assembled and tested surface mount board which provides
easy probe access points to all SP6650 inputs and outputs so that the user can quickly connect
and measure electrical characteristics and waveforms.
The next two sections describe the SP6650 board layout and using the SP6650 evaluation
boards. A table of SP6650 pin assignments is also included with details on input/output pin
function. A SP6650 evaluation board list of materials table is provided with some manufacturers
part numbers to use as a reference. Finally, a schematic and drawings of the PC layout are
included as a design-in tool for the user of the SP6650.
BOARD SCHEMATIC AND LAYOUT
The SP6650 Evaluation Board has been designed for easy and convenient access to all Inputs
and Outputs of the SP6650 device under test. Position the board with the silkscreen lettering
upright, (also see the drawing on the front page of this manual) and you will see the SP6650
MSOP, labeled U1 in the center of the board, and surrounding it the capacitors C
IN
, CV
IN
, CF, C
OUT
and resistors forming the switched DC-DC Converter circuit.
