Distributed Power Unit for P9145

Flexible output current capabilities are key to address modern multi-core SoC solutions with a variety of different skews. The IDT P9147 distributed power units (DPU) operate as additional phases to the P9145 PMIC to increase the output current of the solution. The device works as a controlled current source fully controlled by the host PMIC. Multiple P9147 devices may be used in parallel to provide additional current to the load. A high-speed proprietary interface between the P9145 and the P9147 provides control and feedback information. The device seamlessly integrates into the PMIC eco-system and is flexible and transparent to the user. The P9147 has been designed for systems with high voltage supplies, like 12V ATX based or multi cell battery stack systems.
