Power management ICs (PMICs)

Power management ICs (PMICs) are integrated circuits that include multiple power rails and power management functions within a single chip. PMICs are frequently used to power small, battery-operated devices since the integration of multiple functions into a single chip results in more efficient use of space and system power. Functions commonly integrated into a PMIC include voltage converters and regulators, battery chargers, battery fuel gauges, LED drivers, real-time clocks, power sequencers, and power control.

Low-power PMICs provide the high-efficiency and compact form factors needed for space-constrained applications such as wearables, hearables, sensors, and IoT devices. High-performance PMICs maximize performance per watt while increasing system efficiency for computationally intensive platforms such as systems-on-chip (SoCs), FPGAs, and application processors.

Low-power PMICs

Low-power PMICs provide the high-efficiency and compact form factors needed for space-constrained applications such as wearables, hearables, sensors, and IoT devices. Low operating current, high-efficiency power conversion, and compact form factors are critical for devices that run primarily on small batteries.

PMICs based on the single-inductor, multiple-output (SIMO) architecture use a single inductor as the energy-storage element for multiple, independent DC outputs. The use of fewer inductors can shrink power supply size as much as 50%. In addition, low quiescent current helps to extend the battery life of your space-constrained designs.

Wearable PMICs offer regulators with single-inductor topologies which maximize efficiency. Multiple ultra-low quiescent current regulators with optimal efficiency minimize overall power consumption and extend battery life. By integrating efficient regulation with battery charging, smart power control, and power-optimized peripherals, wearable PMICS provide many options to create space-optimized solutions for always-on battery-operated devices such as fitness monitors, hearables, smart watches, IoT, and wearable clinical devices.

High-performance PMICs

High-performance PMICs maximize performance per watt while increasing system efficiency for computationally intensive platforms such as systems-on-chip (SoCs), FPGAs, and application processors.

Our scalable power-management ICs provide multiple power rails and power management functions while consuming up to 40 percent less power than standard solutions. These high-performance PMICs extend battery life in the most compact form factor. They support a wide variety of applications including augmented/virtual reality (AR/VR), gaming, SSDs, security, industrial IoT, and handheld devices such as cameras.
