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. Figure 4 shows the schematic

of this evaluation board configuration.

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. Figure 5

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. Figure 6 shows the schematic of this

evaluation board configuration.
