DESCRIPTION
The MAX1778 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) Verify that jumper JU1 (SHDN) does not have a
2) Connect a voltmeter to the V1 pad.
3) Connect a +2.7V to +5.5V DC power supply to the
4) Turn on the power supply, and verify that the main
5) Verify that the negative charge-pump regulator out-
6) Verify that the positive charge-pump regulator out-
7) Verify that the LDO output (LDOOUT) is +2.5V.
8) Verify that the V

other output voltages, see Evaluating Other Output
Voltages. The input voltage range is +2.7V to +5.5V
when selecting the output voltage.
The MAX1778 evaluation kit step-up switching regulator
circuit can be configured for an output voltage up to
+13V. A built-in transient load tester (TRANS_LOAD,
CSEN) for the step-up switching regulator allows tran-
sient load tests up to 1A.
Note: Please indicate that you are using the MAX1778,
MAX1880, MAX1881, or MAX1882 when contacting these
component suppliers.
