Primarion, a mixed-signal semiconductor company that designs,
manufactures and markets digital power ICs, today announced the
addition of the dual-output, dual-phase PX7522 to the Primarion
Di-POL(TM) product family of fully programmable digital power
conversion and power management ICs.
The PX7522 is a power conversion and power management IC for
synchronous DC/DC converters in the telecom, datacom, computing and
storage markets. The PX7522 is configured to regulate two independent
outputs, or two phases in a single output mode. It supports both DCR
and RDSon current sense topologies and a wide output range of 0.5V to
8V. This highly configurable control IC utilizes PMBus(TM) and on-chip
non-volatile memory (NVM) for extensive user-friendly control and
real-time system monitoring.
"With the introduction of PX7522, Primarion has taken another
major step forward towards increasing system-level integration," said
Mohan Mankikar, president of Micro-Tech Consultants, a research and
consulting firm specializing in the power electronics market. "The
PX7522's higher level of flexibility, with its dual-output feature and
PMBus compatibility for system communication, will enable OEMs to use
this IC in a very cost-effective manner. This is precisely the type of
product progression that will accelerate market adoption of digital
ICs."
The PX7522's control functions utilize digital technology,
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.
"The PX7522 and the Di-POL product family address two aspects that
are becoming increasingly important to OEMs; the first is time to
market and the second is simple system-level communications," said
Deepak Savadatti, vice president of marketing for Primarion. "A
complete system can quickly and easily be built around the PX7522 and
other members of the Di-POL product family with a simple graphical
user interface (GUI). The GUI enables designers to perform design,
analysis and optimization without having to devote time to software
programming. We are excited to be able to bring such a complete
solution to the market."
Configurations for the PX7522 are easily loaded, edited and saved
to NVM over the device's I2C serial interface using Primarion's 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.
With other technologies, many of these configurable functions
would typically require an external microcontroller. The extensive
flexibility offered by the fully digital control, PMBus interface and
user-friendly GUI allows optimization of the PX7522's power management
performance within an already existing system.
The PX7522 operates on a single +5V supply and has a switching
frequency range of 150KHz to 1MHz. Accurate sharing between phases (in
a single mode operation) enables the flexibility to support
multi-phase operation for increased power requirements. The PX7522
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.
With innovative easy-to-use solutions, offering cost savings and
improved system-level performance, Primarion continues to drive the
future of digital power management and is proving to be the IC vendor
of choice for manufactures in the telecom, datacom, computing, storage
and graphics markets.
