NXP – PMICs provide highly integrated power solution for MCUs or applications processors

NXP_logo_CMYK_00
NXP Semiconductors supplies a wide range of Power Management Integrated Circuits (PMICs), which provide high-performance power- management solutions for various applications in the automotive, consumer and industrial markets.

Use of a PMIC provides a highly integrated alternative to the implementation of a circuit based on multiple discrete components. NXP PMICs integrate power management, system control, battery management, interface and audio functions, as well as other system-specific functions, into a single chip.

They also take advantage of high-performance NXP process technologies to achieve very high efficiency for extended battery life and reduced power dissipation. Each PMIC family is designed to support a specific series of microcontrollers or applications processors. For instance, the i.MX 6, i.MX 6PLUS and i.MX 7 applications processors are supported by the PF0100/ PF0200, PF3000, PF3001 and PF1550 series of PMICs.

Likewise, the VR500 family of PMICs is optimised for NXP’s QorIQ® networking communications processors. VR500 PMICs offer multiple, specially programmed DC-DC and LDO regulator outputs for the ARM® Cortex®-A-based Layerscape 1 and the T1 Power Architecture series processors. In addition, various versions of the VR500 family have been incorporated into reference platforms incorporating the Layerscape 1 processors.

A typical NXP processor application might supply three functional domains:
• The processor and its DRAM main memory. Sophisticated power-management modes implement dynamic voltage and frequency scaling
• Peripherals, such as radios, memories and sensors
• A USB channel, which might require a boost power supply to an output of 5V if the input voltage drops

The NXP PMICs can supply all of these domains from a single chip.
