Maxim Integrated — PMICs for Hearables: Lowest Standby Power and High Efficiency at Less Than Half the Size

FTMJan2018-AS-Maxim-tile-200x200

Size is critical for hearables and wearables as they continue moving to smaller form factors. Most PMICs for these small, lithium-ion battery-operated devices require additional components, such as boost, buck, and low dropout (LDO) regulators; a charger; and current regulators for LED indicators. Designers of Bluetooth® headphones, activity monitors, smart garments, smartwatches, and other size-constrained […]
