Description
The DA9231 is an ultra-low quiescent current high-efficiency buck regulator and an ultra-low quiescent current LDO in a compact I2C configurable WLCSP package targeting battery-powered applications needing highly efficient power supplies.
The buck regulator extends high light-load efficiency down to 10μA further extending battery life. Dynamic Voltage Control (DVC) 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. It provides multiple protection features and comes with the ability to monitor the events and indicators in the GPO pin.
Benefits
- Longer battery life
- Design flexibility through configurability
- Small solution size
- Future-proofing for new technology MCUs with 0.6V min buck output voltage
- Future-proofing for new technology batteries with 2.5V min input voltage
