• Output Current: 20000 mA

The MAX1960 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 jumpers JU1, JU2, and JU3 are shorted
2) Preset input power supply to between 2.7V and
3) Connect the positive power-supply lead to the IN1
4) Connect a voltmeter and load from OUT1 to PGND1
5) Turn on the power supply.
6) Verify that the voltage at OUT1 is +1.8V ±1.5%.

MAX1960 Evaluation Kit
The MAX1960 EV kit comes with the MAX1960
installed, but can also be used to evaluate the
MAX1961 and the MAX1962. Free samples of these
parts can be obtained from Maxim.
To evaluate the MAX1961, first carefully remove U1
from the PC board and replace it with the MAX1961.
Next, remove feedback resistors R3 and R4. Finally,
short the pads of R3. The evaluation kit is now config-
ured for the MAX1961.
To evaluate the MAX1962, a second circuit is provided
on the PC board. Components for this circuit do not
come installed on the standard evaluation kit board. To
configure the board for the MAX1962, install the com-
ponents recommended in the Component List section.
