Norwood, Mass. - Analog Devices, Inc. introduced an ultra-low-power buck regulator that extends battery life in portable devices by offering ultra-light-load power conversion efficiency. Claiming the industry’s highest power efficiency, the ADP5301 buck regulator - with a 90 percent efficiency rating and consuming only 180-nA quiescent current - is designed to deliver maximum power for a longer period of time than previously achievable, according to Analog Devices. This makes the device well suited for Internet of Things (IoT) applications, including wireless sensor networks and wearable devices such as fitness bands and smartwatches.
Key features include a 6.5-V to 2.05-V input voltage range that enables a wide range of battery sources or architectures, integrated voltage supervisory function for increased overall system reliability, and selectable, low-noise forced PWM mode with low output voltage ripple that powers noise-sensitive analog load up to 500-mA output current capability. The new device is housed in a tiny WLCSP package that measures less than 3.1-mm², which makes it suitable for small form factors.
