MAX662A Evaluation Kit
_______________General Description
The MAX662A evaluation kit (EV kit) is an assembled
surface-mount board that allows easy evaluation of the
MAX662A or MAX662. The EV kit schematic is the stan-
dard circuit shown in Figure 3a on page 5 of the
MAX662A data sheet. A 3-pin jumper connector and a
shunt are included to allow easy control of normal-oper-
ation and shutdown modes.

____________Operating Instructions
Pin 1 of the 3-pin jumper connector is tied to ground,
pin 2 is tied to the SHDN pin of the MAX662A, and pin 3
is tied to V CC (Figure 1). Connect the jumper shunt
across pins 1 and 2 of jumper connector J1 for normal
operation. Note: The MAX662A EV kit will be in shut-
down mode if the jumper shunt is not inserted
across J1. The SHDN pin has an internal pull-up to
V CC , and therefore must be connected to ground for
proper operation. Connect the jumper shunt across
jumper connector pins 2 and 3, or simply remove the
jumper shunt to observe shutdown-mode operation.
Observe the power-supply input voltage limits specified
in the data sheet. Do not short the output to ground.
Also, do not excessively load the output—V OUT should
not fall below V CC . If the above conditions are violated,
the device may be damaged.
