Overview
Description
Flexible output current capabilities are key to address modern multi-core SoC solutions with a variety of different skews. The P9148 distributed power units (DPU) operate as additional phases to the P91E0A 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 P91E0A and the P9148A provides control and feedback information. The device seamlessly integrates into the PMIC ecosystem and is flexible and transparent to the user. P9148A has been designed for systems with a single 5V supply available and supports features such as an optional thermal limit warning flag, load current monitor, and automatic load-balancing among phases).
