SIMO Switching Regulators: Extending Battery Life for Hearables and Wearables

Consumers expect hearables, wearables, and other ultra-small electronic devices to be long on battery life despite their tiny form factor. Yet, the device size does limit the battery capacity. This whitepaper discusses how to gain some of that space back by using a switching regulator based on a single-inductor multiple-output (SIMO) power converter architecture. The SIMO architecture, along with the regulator’s low quiescent current, enables the IC to extend battery life for space-constrained electronic products. This whitepaper will help to gain a deeper understanding of SIMO technology and how it works.
