The complete schematic of the ISL97702 OLED driver Demo Board is shown in Figure 1. In order to use the demo board properly, it is necessary to understand the purpose and function of the on board jumpers (JP1, JP2, JP3). In the demo board, jumper JP1 is used to enable ISL97702 through the NEN pin. The part is enabled when the NEN pin is connected to GND through JP1. JP2 is used for the selection of the output voltage feedback network. The pre-installed values of resistors R1, R5 and R6 in the demo board schematic set the selectable output voltages to 18.3V and 12.6V. Either of these two output voltages can be selected by shunting JP2 to either VDD or GND.
