The breakthrough MAX77655 single-inductor multiple output (SIMO) power management IC (PMIC) from Maxim Integrated Products provides the highest-density power solution for extremely compact next-generation devices. This PMIC delivers a 70 percent reduction in solution size compared to the nearest competition, with 700mA across four buck-boost channels and only one inductor required for a total solution size of 17mm2.
Designers of ultra-small portable devices such as wearables, internet of things (IoT) sensor nodes and health monitors are looking to increase computing capability, memory and sensor resources in their feature-rich devices – all in an ever more compact form factor. The MAX77655 SIMO PMIC addresses this space-constraint issue by sharing one inductor among all four supplies in a single 3.95mm2 IC. In addition, ultra-high efficiency helps to extend battery life by providing 90 percent regulator efficiency during moderate to heavy load conditions, while consuming only 6.9µA of quiescent current during light load conditions (more info).
