Exar Corporation introduced the XRP7720 quad-output, synchronous step-down, universal PMIC, which has the ability to be programmed to meet the needs of nearly all systems. In development, an I2C interface allows Exar's PowerArchitectTM design and configuration software to quickly optimize the power system performance. Configurable parameters and functions include: output voltage, full feature up and down sequencing, fault behavior, GPIO functionality and control loop parameters. All are re-configurable through the use of on board FLASH memory.
During qualification, the system engineer has access to the full suite of PowerXR capabilities such as re-configurability, real time dynamic control, and telemetry. Design verification testing can proceed far more rapidly through the leveraging of software with the power system. Once system qualification is completed, the additional cost of the I2C interface and FLASH can be eliminated when dynamic control, telemetry and monitoring are not required in the project. High volume production XRP7720 product is hard programmed by Exar, providing a customized PMIC. If the customer finds the re-configurability, dynamic control, and monitoring of value in the end product they can easily migrate to the pin compatible full featured XRP7724.
