DESCRIPTION
The
SP6680 Evaluation Board
is designed to help the user evaluate the performance
of the SP6680 for use as a single Li-Ion battery input to +5V output DC-DC Converter.
The SP6680 operates from 2.7V to 6.3V input, with the highest efficiency in the range
3.0V to 4.2V where the Li-Ion battery has the most energy. The SP6680UEB
evaluation board is a complete power supply circuit with +5V LDO Regulator to provide
ease of use to evaluate system DC/DC Converter performance.
The evaluation board is a completely assembled and tested surface mount board which
provides easy probe access points to all SP6680 Inputs and Outputs so that the user
can quickly connect and measure electrical characteristics and waveforms.
The next two sections describe the SP6680 Board Layout and Using the SP6680
Evaluation Boards. A table of SP6680 Pin Assignments is also included with details on
input/output pin function. A SP6680 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 SP6680.
BOARD LAYOUT
The
SP6680 Evaluation Board
has been designed for easy and convenient access to
all Inputs and Outputs of the SP6680 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 SP6680
μ
SOIC, labeled U1 in the left center of the board, and
surrounding it the Capacitors Cin, CF1, CF2 and Cout forming the switched capacitor
DC-DC Converter circuit. On the right is U2, the LDO, in a small SOT23-5 package
providing a low-noise, regulated +5V output.
