Multiple-output PMICs

14 November 2018 Power Electronics / Power Management

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.

The MAX17270, MAX77278, MAX77640/MAX77641 and MAX77680/MAX77681 PMICs help to reduce the power management footprint for space-constrained products such as wearables, hearables, sensors, smart-home automation hubs and Internet of Things (IoT) devices.

The chips’ control architecture 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. In addition, the low quiescent current of the PMICs plays an important role in extending battery life. With the intrinsic buck-boost operation of the PMICs, the power rails can operate over a battery’s entire range.
