Analog Devices Max77659 power manager
The Max77659 single-inductor multiple output (SIMO) power management IC (PMIC) with integrated switch-mode buck-boost charger from Analog Devices charges wearables, hearables and other Internet of Things (IoT) devices quickly. It delivers over four hours of play time after a short, 10-minute charge, but uses a single inductor to power multiple rails, potentially reducing the bill of materials by 60%.
The unit integrates a switch-mode buck-boost charger and three independently programmable buck-boost regulators, all sharing a single inductor to minimise total solution size. The regulators extend battery life by operating at 91% efficiency during moderate to heavy load conditions while consuming only 5 µA during light load conditions.
The unit measures just 2.55 x 2.37 mm.
