DA9070 Evaluation
The typical application diagram of DA9070 is shown in
DA9070 includes a Buck regulator, a Boost Regulator, 3x LDO/LDSW, and a linear battery charger.
On DA9070 Fuel gauge EVK, each regulator can be evaluated individually. It is recommended to
follow the operation conditions as shown in
to avoid any damage to the EVK board. For test
and measurement set-up, please refer to
for descriptions of connectors on the EVK board.
