P9148

Distributed Power Unit for P9180A / P9145

Flexible output current capabilities are key to address modern multi core SoC solutions with a variety of different skews. The IDT P9148 distributed power units (DPU) operate as additional phases to the P9180A PMIC and 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 P9148 devices may be used in parallel to provide additional current to the load. A high-speed proprietary interface between the P9180A,  P9145 and the P9148 provides control and feedback information. The device seamlessly integrates into the PMIC eco-system and is flexible and transparent to the user. P9148 has been designed for systems with single 5V supply available and supports additional features compared to P9147 (optional thermal limit warning flag, load current monitor and automatic load-balancing among phases).
