MAX8795A Evaluation Kit
The MAX8795A EV kit’s step-up switching-regulator
output, limited by the built-in 20V n-channel MOSFET, is
set to +14V through feedback resistors R1 and R2. To
generate output voltages other than +14V (1.2 x V
+18V), select different external voltage-divider resistors
(R1 or R2). Refer to the Output-Voltage Selection sec-
tion in the MAX8795A IC data sheet for instructions on
selecting the feedback resistors.
The MAX8795A EV kit’s positive linear-regulator output
is set to +25V by feedback resistors R3 and R4. To
generate output voltages other than +25V (+1.25V to
nearly the positive charge-pump output voltage), select
different external voltage-divider resistors (R3 or R4).

Refer to the Output-Voltage Selection section in the
MAX8795A IC data sheet for instructions on selecting
the resistors.
The MAX8795A EV kit’s negative linear-regulator output
is set to -10V by feedback resistors R7 and R8. To gen-
erate output voltages other than -10V (0 to nearly the
negative charge-pump output), select different external
voltage-divider resistors (R7 or R8). Refer to the
Output-Voltage Selection section in the MAX8795A IC
data sheet for instructions on selecting the resistors.
The MAX8795A EV kit’s op amps (OUT1–OUT5) are
designed to drive the LCD backplane. Using external
voltage-divider resistors, each op amp is configured to
one-half of VMAIN’s output voltage. To generate output
voltages other than +7V, select different external volt-
age-divider resistors (R11–R20).
