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 these pins 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 6.0 V.
between these pins 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 6.0 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.

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 6.0 V.

Output Connectors
4.2.1
J4 – VOUT
This header is the positive connection of the output voltage. Connect the load between these pins and J6
(GND).

4.2.2
J5 – Output Sense Connector
This header is intended to measure the output voltage directly on the output capacitors.
4.2.3
J6 – GND
This header is the return connection of the output voltage. Connect the load between these pins and J4
(VOUT).

4.3
Other Connectors
4.3.1
J7 – Power Good Connector
The Power Good Output (PG) of the IC is an open-drain output and there is a 1 M
Ω
resistor connected
between PG and VOUT. Pin 1 of this connector is connected to PG and Pin2 is connected to GND.
4.4
Jumpers
4.4.1
JP1 – Enable Jumper
Placing a jumper across pins EN and ON ties the EN pin to VIN, thereby enabling the device. Placing a
jumper across pins EN and OFF ties the EN pin to GND, which disables the device.
