Description
General part information
DA9233 Series
The DA9233 is a high-efficiency, ultra-low quiescent current buck regulator and ultra-low quiescent current LDO in a compact I²C configurable WLCSP package. The buck regulator also features ultra-low output ripple (<10mV). It targets battery-powered applications needing low ripple and highly efficient power supplies.
The buck regulator extends high light-load efficiency down to 20μA 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.
