EVALUATION BOARD CONFIGURATIONS
The ADP1712/ADP1713/ADP1714 evaluation boards come
supplied with different components depending on which
version is ordered. Components common to all versions are
C1, C2, and J1.
ADP1712 FIXED OUTPUT WITH SOFT START
Evaluation boards that come supplied with the ADP1712 fixed
output voltage option devices has the additional C3 soft start
capacitor. This capacitor controls the rise time when the output
voltage starts up.
Figure 3 shows the schematic of this evalua-
tion board configuration.

ADP1712 ADJUSTABLE OUTPUT
Evaluation boards that come supplied with ADP1712 adjustable
output voltage option devices have the additional R1 and R2
resistors to set the output voltage.

ADP1713 FIXED OUTPUT WITH BYPASS
Evaluation boards that come supplied with ADP1713 fixed
output voltage option devices has the additional C3 bypass
capacitor to reduce the output noise and improve PSRR.

ADP1714 FIXED OUTPUT WITH TRACKING
Evaluation boards that come supplied with ADP1714 fixed
output voltage option devices with tracking do not have C3,
R1, or R2 populated. The user can instead connect an external
voltage to the SS/ADJ/BYP/TRK pad of the evaluation board
to use the track function.
