DA9230中文资料Nanopower Buck Regulator for Low Power Connected Devices数据手册Renesas规格书

描述 Description

The DA9230 is an ultra-low quiescent current, high-efficiency buck regulator in a compact I2C configurable WLCSP package targeting battery-powered applications needing highly efficient power supplies. The battery life of these devices is significantly improved due to the low quiescent current delivered by DA9230 during operation and shutdown.

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 DA9230 provides multiple protection features and comes with the ability to monitor the events and indicators in the GPO pin.
