Torrance, Calif.—Primarion's PX7510 controller, the first product in the company's Di-POL product family of power management ICs, digitally implements all functions for monitoring and control of point-of-load (nonisolated) converters in datacom, telecom, and computing applications.
"The PX7510 utilizes Primarion's digital technology to create a power solution that offers flexibility, adaptability and PMBus communication in a single chip that cannot be accomplished in the analog world for the same cost and density," said Milan Jovanovic, chief technical officer of the Power Systems Business Group of Delta Electronics. "The partnership between Delta and Primarion has been instrumental in the definition of the PX7510 controller. The PX7510 specification meets the highest levels of power management requirements for the 'point-of-load' markets while setting a new standard for digital and analog power solutions in the marketplace."
Configurations for the PX7510 are loaded, edited, and saved to on-chip nonvolatile memory (NVM) over the device’s I2C serial interface using the company's graphical user interface (GUI). With configurations stored on the IC, the controller performs real-time adjustments to the designer’s previously configured settings and thus optimizes performance accuracy without the delay of accessing outside memory storage.
Chip features include single-pin current sharing for multiphase POL operation; digital control loop and active voltage positioning; PMBus-compatible serial interface (library of 60 core PMBus commands); control of output margining over the serial interface; internal voltage and temperature referencing; internal oscillator; current, temperature and 12-volt sense telemetry; configurable PWM generator; and comprehensive fault protection and reporting. The PX7510 operates from a single 5-volt supply.
