This section describes the hardware connection of the Daughter Board with the
Explorer 16 Development Board. Figure 2-3 displays the Daughter Board hardware
connection (MPLAB ICD 2 and power supply) to the Explorer 16 Development Board.

The dsPIC33FJ16GS504 SMPS device controls both buck stages (Buck 1 and Buck
2), as well as the boost stage through the Explorer 16 Development Board
simultaneously.

The potentiometer R6 (10 k
Ω), in series with the R12 resistor on the Explorer 16
Development Board, is connected to analog input channel (AN5) of the SMPS dsPIC
DSC device. The potentiometer R6 on the Daughter Board is connected to the analog
input channel (AN10) through the J10 jumper. Both potentiometers can be used for
development purposes to simulate any feedback signal.

Note:
To operate all three converters using the Explorer 16 Development Board,
ensure that J12, J13 and J6 are shorted with the jumper header, and J14
and J15 are open before powering up the board.
