MAXM38643A EMGA
Evaluation Kit
Evaluates: MAXM38643
General Description
Quick Start
Required Equipment
The MAXM38643A EMGA evaluation kit (EV kit) evaluates
the MAXM38643A IC in an EMGA package. The
MAXM38643A is an ultra-low quiescent current step-down
DC-DC converter. The EV kit operates over an input range
of 1.8V to 5.5V and provides resistor-configurable output
voltages from 0.7V to 3.3V. The EV kit delivers up to
600mA of current. The EV kit comes with the
MAXM38643AEMB+ installed.

2. Connect the 5.5V power supply between the IN and
nearest GND terminal posts.
3. Connect the 600mA electronic load between the OUT
and nearest GND terminal posts.
4. Connect the DVM between the OUT and nearest GND
terminal posts.
5. Turn on the power supply.
6. Enable the electronic load.
