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.

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

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

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

not fall below V

the device may be damaged.
