Analog Devices introduced an ultra-low-power buck regulator that extends battery life in portable devices by achieving the industry’s highest ultra-light-load power conversion efficiency.
With a 90% efficiency rating and consuming only 180 nA quiescent current, the ADP5301 is designed to deliver maximum power for a longer period of time than previously achievable and is ideally suited for Internet of Things (IoT) applications, including wireless sensor networks and wearable devices such as fitness bands and smartwatches.
The device is housed in a tiny WLCSP package that measures less than 3,1 mm², which makes it suitable for small form factors. Its 6,5 V to 2,05 V input voltage range supports a wide range of battery sources or architectures, while an integrated voltage supervisory function increases overall system reliability. Selectable, low-noise forced PWM mode with low output voltage ripple powers a noise-sensitive analog load up to 500 mA output current capability.
