CHANGING THE OUTPUT VOLTAGE
The ADP1864-EVALZ evaluation board output regulation
voltage can be changed by altering the voltage divider consisting
of RF2 and RF1. The output regulation voltage is determined by
the following equation:
V _OUT
=
0.8
×
⎜⎜⎝⎛
R_F
2 ^{+ R}F1
R_F1
⎟⎟⎠⎞

Modifying the output voltage changes the inductor ripple
current and subsequently the output voltage ripple, transient
response, and stress on the PFET. The design tool considers this
and, if necessary, provides new component values.
