7.2 Terminal Descriptions

Terminals Description
PVIN Connect the power supply between this terminal and the GND terminal beside it. The device is rated between 3 V to 18 V. The absolute maximum voltage rating is 22 V.
GND The GND terminals are meant to provide close return paths to the power and signal terminals besides them. They are all connected together on board.
SW SW is connected to the switch node of the power stage. It can be used to monitor the switch node waveform by a scope.
VOUT VOUT terminal is connected to the output capacitor on the board and should be connected to the load
FB FB terminal is connected to the FB pin of the LM10500. It can be used to monitor the AVS voltage command programmed by PWI. Careful not to add any noise to the FB terminal or load it by any means.
AVIN_EXT External AVIN supply. Connect AVIN to AVIN_EXT on JP2 to power AVIN externally.
SYNC Synchronizing clock input. When J2 is Closed, switching frequency is controlled by the on board resistor R20. When J2 is Open, the switch node waveform will be synchronized to the clock source connected to SYNC terminal.
PWROK This terminal connects to the PWROK pin of the LM10500. PWROK is pulled up to 2.5V through a 10-kΩ resistor.
VPWI_EXT External VPWI supply. Connect VPWI to VPWI_EXT on JP2 to power VPWI externally.
J4 J5 J6 Connectors to the USB2PWI board shown in Section 8.2; see Section 8.2.
J1 Connector to monitor AVS signal or to an external controller; see Section 8.3.
