This header is the positive connection to the input power supply and is tied to the ICs VIN pin. The power
supply must be connected between J1 and J3 (GND). The leads to the input supply should be twisted and
kept as short as possible. The input voltage must be between 1.6-V and 6-V.

Although not installed, this header provides Kelvin sense connections across the input capacitor C1.
This header is the return connection to the input power supply and is tied to the ICs GND pin. The user
must connect the power supply between J3 and J1 (VIN). The leads to the input supply should be twisted

This header connects to the pin that is the output of the non-synchronous boost converter before the
input-to-output isolation switch. Unless the modifications in section 3.2 are made, this header should only
be used for measuring the boost converter output voltage prior to the input-to-output isolation. If the
modifications in section 3.2 are made, then the output voltage at this header is the regulated output
voltage and the user can apply external loads between J4 and J6 (GND).

Pin one of this jumper connects to the IC's EN pin. When its shunt is installed, this jumper ties the EN pin
to VIN thereby turning on the boost converter. The isolation switch also turns on and connects pins VO
(J4) and OUT (J7). Removing the shunt from this jumper allows its internal pull down resistor to pull it to
ground thereby disabling the converter and disconnecting VO (J4) and OUT (J7).
