The MAX761 EV kit is fully assembled and tested.
Follow these steps to verify board operation. Do not
turn on the power supply until all connections are
completed.
1) Connect a 5V power supply to the pad marked VIN.
2) Connect a voltmeter and load (if any) to the VOUT
3) For normal operation, place the shunt across pins
4) Turn on the power supply and verify that the out-

The MAX761 EV kit is configured for bootstrapped
mode. In bootstrapped mode, the MAX761 is powered
from the output voltage, which increases efficiency at
lower input voltages and requires fewer components.
Refer to the Bootstrapped/Non-Bootstrapped Mode sec-
tion of the MAX761 IC data sheet for further details. For
an adjustable output in bootstrapped mode, refer to the
Output Voltage Adjustment section.
