Primarion Introduces Dual-Phase, Programmable Digital Power Conversion and Power Management IC
Primarion Inc. announced the addition of the dual-phase PX7520 to the Di-POL™ product family of fully programmable digital power conversion and power management ICs. The all-digital PX7520 is a dual-phase power conversion and power management IC for non-isolated dc–dc converters in telecom, datacom, computing and storage markets. This highly configurable digital control IC utilizes PMBus™ and on-chip non-volatile memory (NVM) for extensive user-friendly control and real-time system monitoring.
"The largest and fastest-growing portion of the worldwide digital power IC market is expected to be the power conversion and power management area targeted by Primarion with the Di-POL product line," said Jeff Shepard, founder and President of Darnell Group. "Our latest analysis projects that segment will grow from $14 million in sales this year to almost $400 million by 2011 – a five-year growth rate of 95 percent per year."
The PX7520 utilizes digital technology to implement all control functions, providing the ultimate in adaptable, stable and flexible solutions at an increased output load. By incorporating an industry standard I2C PMBus serial interface for control and monitoring, Primarion enables the power supply designer to quickly optimize designs and monitor real-time system performance. Configurations for the PX7520 are easily loaded, edited, and saved to NVM over the device's I2C serial interface, using Primarion's graphical user interface (GUI). With configurations stored on the IC, the controller can perform real-time adjustments to the designer's previously configured settings and thereby optimize performance accuracy without the delay of accessing outside memory storage.
The PX7520 operates on a single +5V supply and has a switching frequency range of 150KHz to 2MHz. Accurate current sharing between phases and with other members of the Di-POL family, including PX7510, enables the flexibility to support any multi-phase operation for increased power requirements. The PX7520 provides superior accuracy through internal calibration that measures and corrects system-level current sense error sources upon startup. The programmable current sense temperature compensation allows the designer to tailor the response for the best accuracy over temperature.
Already sampling with top-tier customers, the Primarion PX7520 is now available for general sampling. The PX7520 is available in a RoHS-compliant, 5mm-x-5mm 32-lead Micro Lead Frame (MLF) package.
