Analog Devices / Maxim Integrated MAX20303 Wearable Power Management Solution

Analog Devices MAX20303 Wearable Power Management Solution is a programmable power solution designed for ultralow-power wearable applications. The Analog Devices MAX20303 offers a high-efficiency solution for increased efficiency and a minimal footprint to reduce design size. A flexible set of power-optimized voltage regulators provides a high level of integration for a fully optimized power architecture. The quiescent current of each regulator is specifically suited for 1μA (typ.) to extend battery life in always-on applications.
