Nanopower PMIC with ultra-low ripple buck regulator for low power connected devices

DA9233 is a high efficiency, ultra-low quiescent current buck regulator and ultra-low quiescent current LDO in a compact I²C可配置WLCSP包。巴克监管机构一lso features ultralow output ripple (<10mV). It is targeting battery powered applications needing low ripple and highly efficient power supplies.

The buck regulator extends high light load efficiency down to 20 μA 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.

The low quiescent current LDO can be configured as a Load Switch and provides the second supply output. The LDO’s uncommitted inputs can be connected to either the battery or the buck output. Connecting the input to the buck output provides the flexibility to improve the PSRR at the LDO output as needed.

DA9233 provides multiple protection features and comes with the ability to monitor the events and indicators in the GPO pin.
