The MAX831 EV kit is a fully assembled and tested sur-
face-mount board. Follow the steps below to verify
board operation.
Do not turn on the power supply
until all connections are completed.
1) Connect an 8V to 30V supply to the pad marked
VIN. The ground connects to the GND pad.
2) Connect a voltmeter and load (if any) to the VOUT
pad.
3) Remove the shunt on J 1 for normal operation.
4) Turn on the power and verify that the output
voltage is 5.0V.
Instructions for modifying the board for different output
voltages appear in the sections Evaluating the MAX832
and MAX833 and Other Output Voltages.
_______________Detailed Desc ription
J umper S elec tion
The two-pin header J 1 selects the shutdown mode.
Table 1 lists the jumper selectable options.
Table 1. Jumper J1 Functions
Notes about Induc tor S elec tion
The 100μH Coilcraft D03316-104 inductor that comes
mounted with the EV kit has low resistance and a medi-
um current rating (1.3A). It provides excellent perfor-
mance over the line and load ranges of the
MAX830/MAX831/MAX832/MAX833.
For additional information on inductor selection, refer to
the MAX830–MAX833 data sheet.
Evaluating the MAX 832 and MAX 833
The MAX831 can be replaced by a MAX833 to gener-
ate a 3.0V output voltage with output current up to 1A,
or by a MAX832 to generate a 3.3V output voltage with
output current up to 1A. The only modification required
is to replace the IC.
