The P9415-R firmware provides great flexibility to customize operating parameters for custom applications.
Default values of the P9415-R operating parameters such as output voltage, FOD parameters, and current limit
are set in the firmware programmed into the internal multi-time programmable (MTP) memory. Based on the end
application, the P9415-R operating parameters can be configured by either writing to internal SRAM registers or
program parameter permanently to internal MTP memory via the I2C interface.
Connect the USB-Bridge dongle to PC via USB connector. Attach the Bridge to the I2C terminal J1 dongle on
the P9415-R EVK DEMO board as shown on Figure 8. The dongle should only be plugged-in in one direction,
extending away from the P9415-R EVK PCB, and dongle cable black line (ground) should be connected in J1
Pin3 GND.
