PMIC'er til den seneste generation af mobile processorer

Dialog Semiconductor er klar med en ny serie af power management IC'er, der sigter mod den seneste geneation af ARM Cortex baserede multi-core applikationsprocessorer samt højt ydende SoCs, FPGA'er og GPU'er (in english).

Dialog Semiconductor, a leading provider of power management, charging, AC/DC power conversion, Wi-Fi and Bluetooth low energy technology, has introduced a new power management product family of four new sub-PMICs that offer best-in-class transient response and in-circuit digital programmability, in a smaller form factor than current market solutions.

The new product family of Buck converters, which consists of the DA9217, DA9220, DA9121 and the DA9122, represents Dialog’s first sub-PMIC family with a 4MHz switching frequency that reduces inductor size and height to allow use of smaller external components. The devices are ideal for ARM Cortex based multi-core application processors and high-performance SoCs, FPGAs and GPUs, which enable developers to fit a 6 to 10 Amp power solution into limited board areas of next-generation devices spanning smartphones, tablets, notebooks PCs, DSLR cameras, solid state drives and more.

The devices drive higher efficiency without sacrificing functionality, simplifying complex system sequencing with digital programmability and configurability, for a seamless interface to the system microcontroller depending on the system requirements. The devices can support a single output up to 6A/10A or dual outputs up to 3A/5A per output, making it ideal for the latest 7nm based SoCs.

Leveraging Dialog’s power conversion prowess, the devices were optimized for users requiring high current with maximum efficiency. The sub-PMICs can run from a single cell Li-ion battery, 3.3V or 5V power supplies. The I2C interface enables dynamic voltage control to optimize power savings and performance, while the fault protection features also provide overvoltage, overcurrent and thermal shutdown protection.

- Designers continue to face new challenges with each passing year when it comes to power consumption and system size but are often forced to trade one feature for another. These new devices are addressing these challenges head on which continue to demonstrate Dialog’s leadership within configurable power management solutions, says Scott Brown, VP Marketing of Dialog’s Advanced Mixed-Signal Business Group.
