Connector and Test Point Descriptions
4.1
Input Connectors
4.1.1
J1 – VIN
This header is the positive connection to the input power supply. The power supply must be connected
between J1 and J3 (GND). Twist the leads to the input supply, and keep them as short as possible. The
input voltage has to be between 2.3 V and 5.5 V.
between J1 and J3 (GND). Twist the leads to the input supply, and keep them as short as possible. The
input voltage has to be between 2.3 V and 5.5 V.
4.1.2
J2 – Input Sense Connector
This header is intended to measure the input voltage directly on the input capacitor. Therefore, a 4-wire
power and sense supply can be connected. Twist the leads to the sensing connector.
power and sense supply can be connected. Twist the leads to the sensing connector.
4.1.3
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.

Output Connectors
4.2.1
J4 – OUTP
This header is the positive connection of the output voltage of the boost converter. Connect the boost
converter's load between J4 and J6 (GND).

J5 – OUTP Output Sense Connector
This header is intended to measure the output voltage of the boost converter directly on the output
capacitors.

4.2.3
J6 – GND
This header is the return connection of the output voltage of the boost converter. Connect the boost
converter's load between these pins and J4 (VOUT).
converter's load between these pins and J4 (VOUT).
4.2.4
J7 – OUTN
This header is the negative connection of the output voltage of the boost converter. Connect the boost
converter's load between J7 and J9 (GND).

J8 – OUTN Output Sense Connector
This header is intended to measure the output voltage of the boost converter directly on the output
capacitors.

4.2.6
J9 – GND
This header is the return connection of the output voltage of the boost converter. Connect the boost
converter's load between these pins and J4 (VOUT).
converter's load between these pins and J4 (VOUT).
4.3
Additional Jumper and Connector
4.3.1
JP1 – Enable
This is the enable pin for both converters. Placing a jumper across pins 2 and 3 shorts the EN pin to GND
(off), thereby disabling the device. Placing a jumper across pins 1 and 2 shorts the EN pin to VIN (on),
thereby enabling the converter.
