Schematic of Demo Board

A schematic of NCP6324B/C evaluation board is shown

in Figure 2, which is for a typical application with 1.8 V
output voltage. It is flexible to configure the board for both
PG devices (NCP6324B) and Mode devices (NCP6324C).
Please refer to Jumper Configuration for details.
