Wearables and hearables are the target for a power chip from Maxim, whose wafer-scale package allows a sub-30mm2 solution, it claims. On board the chip, called MAX77654, is a single-inductor triple-output buck-boost regulator that can provide outputs from 0.8V to 5.5V, two 100mA LDOs, a Li-ion-Li-poly charger, three GPIOs and a watchdog timer. Quiescent power is 6μA ...
