Smart watch PMIC has triple-output single-inductor buck-boost dc-dc converter

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 ...

SMD part sucks heat from hot spots

Vishay has released a series of surface-mount thermal jumper chip that transfer heat from electrically isolated components by providing a thermal conductive pathway to a ground plane or common heatsink. Called THJP and branded ThermaWick, they have an aluminium nitride substrate with 170W/mK thermal conductivity. By pulling heat across the electrical isolation barrier, they reduce the temperature ...
