The MAX8728 EV kit’s step-up switching-regulator out-
put (AVDD) is set to +13.5V by feedback resistors R7
and R8. To generate output voltages other than +13.5V

Up Regulator Design, Output Voltage Selection section
in the MAX8728 data sheet for instructions on selecting
resistors R7 and R8.
The positive charge-pump output (VSRC) is set to +28V
by voltage-divider resistors R14 and R15. To set VSRC to
