Prolong Your Smart Watch Lifetime with SIMO

Abstract: This design solution discusses the advantages of powering a smart watch with a highly integrated PMIC based on the single-inductor multiple output (SIMO) architecture. We compare it to a typical solution with low level of integration which leads to inefficiencies in PCB space and power consumption. Thanks to a unique SIMO architecture, the MAX77654 PMIC delivers more power efficiently in a smaller space, enabling longer battery life and smaller form factor for smart watches and other wearables.
