MAX831 Evaluation Kit
_______________General Description
The MAX831 evaluation kit (EV kit) provides a regulated
5.0V output voltage while operating on input voltages
from 8.0V to 30V. It drives loads up to 1A with conver-
sion efficiency greater than 80%.
The MAX831 EV kit is a fully assembled and tested sur-
face-mount printed circuit board. This kit comes with a
5V-output MAX831 IC, but it can also be used to evalu-
ate the MAX833 (3.0V output), MAX832 (3.3V output),
or MAX830 (adjustable output). Additional pads are
provided on the board's solder side to accommodate
the external feedback resistors used with the MAX830.
