Maxim's SIMO PMICs Shrink Power Regulator Size in Half for IoT Devices

Designers of small, battery-powered electronics can enhance the user experience by extending battery life and further shrinking device size with six new low-power power-management integrated circuits (PMICs) from Maxim Integrated Products, Inc.
The MAX17270, MAX77278, MAX77640/MAX77641 and MAX77680/MAX77681 PMICs help to reduce the power-management footprint by up to 50 percent for space-constrained products such as wearables, hearables, sensors, smart-home automation hubs and internet of things (IoT) devices. They increase the overall system efficiency by nine percent compared to the closest competitive solution, while also reducing heat dissipation, an important consideration for wearable products that make skin contact.

The unique control architecture in the MAX17270, MAX77278, MAX77640/MAX77641 and MAX77680/MAX77681 PMICs allows a single inductor to serve as the critical energy-storage element for multiple, independent DC-rail outputs. This allows engineers to reduce the number of bulky inductors in their designs, thereby improving efficiency, shrinking form factor and reducing heat dissipation (more info).
