DESCRIPTION
The
SP6644/6645 Evaluation Board
is designed to help the user evaluate the performance of
the SP6644/6645 for use as a single or dual cell input to +3.3V output DC-DC Converter. The
output of the SP6644/6645 is preset to +3.3V or can be adjusted from +2V to +5.5V by
manipulating two external resistors. The SP6644/6645UEB evaluation board is a complete
power supply circuit with an option for adding a small SOT23 5-pin +3V LDO Regulator to
provide even better regulation and low noise output.
The evaluation board is a completely assembled and tested surface mount board which
provides easy probe access points to all SP6644/6645 Inputs and Outputs so that the user can
quickly connect and measure electrical characteristics and waveforms.
The next two sections describe the SP6644/6645 Board Layout and Using the SP6644/6645
Evaluation Boards. Power Supply Data is supplied as measured from a typical SP6644/6645
evaluation board. The SP6644/6645 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 SP6644/6645.
BOARD LAYOUT
The
SP6644/6645 Evaluation Board
has been designed for easy and convenient access to all
Inputs and Outputs of the SP6644/6645 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 U1 the SP6644/6645 8-pin
μ
SOIC, in the center left of the board. To the left of U1 are the
input capacitor C1 and the Vbatt pin. To the right of U1 are the output capacitor C2 and the
Vout post. Above U1 is the inductor L1 and the LX test point.
