DA9232

High Efficiency, Ultra-Low Quiescent Current and Ultra-

Low Output Ripple Buck Regulator

General Description

DA9232 is a high efficiency, ultra-low quiescent current and ultra-low output ripple buck regulator in a

compact I²C configurable WLCSP package targeting battery powered applications needing low ripple

and highly efficient power supplies.

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

DA9232 during operation and shutdown.

The buck regulator extends high light load efficiency down to 10µA 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.

DA9232 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 DA9232 comes in a 1.70 mm x 1.30 mm x 0.5 mm,

12-pin WLCSP package.
