Analog - Ultra low-power buck regulator boosts battery life for IoT applications

ADI has introduced an ultra-low-power step-down regulator that extends the battery life of portable devices by achieving the industry's highest ultra-light load power conversion efficiency. The ADP5301 buck regulator is rated at 90% efficiency and quiescent current of only 180nA. It is designed to provide maximum power for longer than previously achievable, making it ideal for Internet of Things (IoT) applications, including wireless sensor networks and the The company says wearables, such as fitness bands and smart watches. The new device uses a small WLCSP package with a size of less than 3.1 square millimeters, which is suitable for small size designs.
