Evaluates: MAX77348A, MAX77348B
in WLP Package
General Description
The MAX77348 evaluation kit (EV kit) provides a proven
design to evaluate the MAX77348, a 3.5 W buck-boost
converter. The IC is capable of 2.3 V to 5.5 V input, and its
output voltage is adjustable between 2.5 V to 4.8 V. The
factory default output voltage of this EV kit is set at 4.5 V.
Output voltage can be adjusted through the software GUI.
The EN pin supports hardware or software enabling of the
device. The EV kit is compatible with any version of the
MAX77348 WLP IC (MAX77348AEWE+ is the default).
