Connector and Test Point Descriptions
3.1
Input Connectors
3.1.1
J1: VIN
This header is the positive connection to the input power supply. The power supply must be connected
between these pins and J3 (GND). Twist the leads to the input supply and keep them as short as possible.
The input voltage must be between 2.3 V and 5.5 V.
between these pins and J3 (GND). Twist the leads to the input supply and keep them as short as possible.
The input voltage must be between 2.3 V and 5.5 V.
3.1.2
J2: Input Sense Connector
This header is intended to measure the input voltage directly on the input capacitor. Therefore, a four-wire
power and sense supply can be connected. Twist the leads to the sensing connector.

3.1.3
J3: GND
This header is the return connection to the input power supply. Connect the power supply between these
pins and J1 (VIN). Twist the leads to the input supply and keep them as short as possible. The input
voltage must be between 2.3 V and 5.5 V.
