Auxiliary Input Power Connector
The Daughter Board can be connected to the auxiliary/bench power DC source through
the J9 input connector. Jumper J6 should be removed while working with the
auxiliary/bench power DC source. See Figure A-5 for the location of this jumper.

PMBus Interface Connector J3
The Daughter Board allows the user to implement the PMBus on the SMPS dsPIC
DSC device using the J3 connector. See Figure A-6 for the location of this jumper.

Note:
The Daughter Board only consists of the three power trains of the DC/DC
converter sections. Either the 16-bit 28-pin Starter Development Board with
the dsPIC33FJ16GS502 device, or the Explorer 16 Development Board
with the dsPIC33FJ16GS504 device can be used to control the DC/DC
power sections of the Daughter Board. The J1 and J2 connectors provide
the necessary signals for control purposes.
