5 Connector and Test Point Descriptions
5.1 Input/Output Connections
The connections points are described in the following paragraphs.
5.1.1 J1 – VIN
This header is the positive connection to the input power supply. Twist the input supply and GND leads to
the input supply and keep them as short as possible.
5.1.2 J2 – S+/S-
This header provides a Kelvin connection across the input capacitor (C1) for more accurate input voltage
measurements.
5.1.3 J3 – GND
This header is the return connection to the input power supply.
