EVAL-ADP5020

DAUGHTERBOARD

The ADP5020 evaluation daughterboard is designed to quickly
evaluate key parameters of the ADP5020 IC. The board layout
footprint is extended so that parts can be exchanged easily, and
headers are available to measure currents using a current probe
or ammeter.

Connect a power supply or Li-Ion battery with 2 A capability
to VBATT. Up to 1.8 A (nominal) can be drawn from the
battery; therefore, short thick cables are recommended to
minimize the IR drops. A high current can cause a big IR drop,
and VBATT can be low enough to put the part into UVLO.
