DA9230

Ultra-Low Quiescent Current Buck

General Description

DA9230 is an ultra-low quiescent current, high efficiency buck regulator in a compact I²C

configurable WLCSP package targeting battery powered applications needing highly efficient power

supplies.

The battery life of these devices is significantly improved due to the low quiescent current delivered

by DA9230 during operation and shutdown.

The buck regulator extends high light load efficiency down to 10 uA further extending battery life.

Dynamic Voltage Control in the Buck regulator facilitates optimization across the system power

modes enabling further improvement in System efficiency and battery life.

DA9230 provides multiple protection features and comes with the ability to monitor the events and

indicators in the GPO pin.

Suitable for space constrained applications, the DA9230 comes in a 1.65 mm x 1.25 mm, 12-pin

WLCSP package.
