Resources for DA9232
Description
The DA9232 is a high-efficiency, ultra-low quiescent current and ultra-low output ripple buck regulator in a compact I2C configurable WLCSP package targeting battery-powered applications needing low ripple and highly efficient power supplies.
The battery life of these devices is significantly improved due to the low quiescent current delivered by DA9232 during operation and shutdown. Dynamic voltage control (DVC) in the buck regulator facilitates optimization across the system power modes enabling further improvement in system efficiency and battery life.
Benefits
- <10mV output ripple exceeds requirements for powering GPS chipsets in wearable devices
- Low quiescent current buck regulator extends battery life
- Dynamically programmable output voltage optimizes performance in operating modes and extends battery life in storage modes
