Power Management ICs (PMIC)

Infineon’s power management IC (PMIC) portfolio covers a wide range of embedded applications for IoT, automotive, industrial and consumer products. Our innovative power management technology solutions enhance the performance and reliability of electronic systems.

Compact, High Performance and Easy-to-Design solutions best suited for your application:

Compact

Infineon power management ICs consume very little low and are highly integrated. These features enable you to design a compact solution. What’s more, the low power consumption allows you to use smaller energy harvesting devices for battery-free IoT applications such as wireless sensor nodes (WSNs). Additionally, the integration of multiple power management regulators, serial communication interfaces and various features for System Safety Functions also minimizes board space.

High performance

Infineon power management ICs extend battery life because they are highly efficient, and have low quiescent current. They are also reliable and robust, helping to protect automotive electronic control units against extreme battery fluctuations that can adversely affect electrical systems.

Easy-to-Design

Infineon power management ICs simplify system designs by reducing external discrete components. Infineon provides easy-to-use evaluation kits to accelerate system design.

PMBus PMIC (Industrial)

Infineon’s integrated power management IC is a five output Point of Load (POL) digital voltage regulator for FPGAs, ASICs, and other multi-rail power systems. The fully integrated PMIC solution replaces multiple regulators with a single device in a compact package. It is a perfect fit for current and future applications in high density ASIC and FPGA. Additional applications include CPU multi-rail systems, embedded computing systems, and communication and storage systems.

The IRPS5401 is designed for single rail operation ranging from 5 V to 12 V, where most PMICs are only 5 V. It has one 500 mA LDO output and four configurable switching regulator outputs (two at 2 A and two at 4 A). The outputs of the IRPS5401 can be used to provide the typical rails required for core, memory, and I/O voltages. All outputs are well within the power requirements of most FPGAs and ASICs ranging between 10 W to 50 W, including integrated voltage sequencing. Industry standard PMBus commands provide an easy-to-use interface for status and telemetry, and PMBus can be used to configure the output voltages in 5 mV steps.

Automotive Power Management ICs (PMICs)

Infineon automotive power management ICs (PMICs) provide highly-integrated and robust power management solutions for automotive applications. The PMICs support comprehensive power supply for the system by a small form factor and complement Infineon’ solution with Traveo™ automotive MCU family. Boost function integrated in the PMICs avoids system blackout under extreme battery voltage fluctuations. Low quiescent current of the PMICs reduce standby current of always-on functions. The PMICs comply with AEC-Q100, and rich system safety functions help to comply with modern vehicle ECU requirements.
