The DA9231 from Renesas is a Buck Regulator and LDO Voltage Regulator IC that is designed for battery-powered applications requiring highly efficient power supplies. It requires an input voltage of 2.5 - 5.5 V and provides an output voltage of 0.6 - 1.9 V. This power management IC (PMIC)’s buck regulator uses dynamic voltage control (DVC) to facilitate optimization across the system power modes, enabling further improvement in system efficiency and battery life. It can configure the LDO regulator as a load switch to provide the second output supply voltage.
This PMIC includes an I2C interface for device configuration and control. It benefits from protection features and system monitoring to ensure high reliability. It is available in a wafer-level package that measures 1.65 x 1.25 mm and is ideal for wearables like wristwear, hearables, smart devices like thermostats and door locks, smoke detectors, portable medical devices, remote sensors and space-constrained applications.
