4) Verify that a shunt is installed on jumper JU1.
5) Verify that a shunt is installed on pins 2-3 on
6) Turn on the DC power supply.
7) Enable the load.
8) Verify that the voltmeter displays 1.5V.
The MAX15118 EV kit provides a proven design to
evaluate the MAX15118 high-efficiency, 18A, step-down
regulator with integrated switches. The applications
include distributed power systems, portable devices,
and preregulators. The EV kit is preset for 1.5V output
at load currents up to 18A from a 2.7V to 5.5V input
supply. The device features a 1MHz fixed switching
frequency, which allows the EV kit to achieve an all-
ceramic capacitor design and fast transient responses.
Input aluminum electrolytic capacitors (C22, C27) are
provided to damp the input if long wires are used; they
are not required in a tight system design.
