概要
説明
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 P9180A and P9145 PMICs 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 P9148 provides control and feedback information. The device seamlessly integrates into the PMIC ecosystem 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 the P9147 (optional thermal limit warning flag, load current monitor, and automatic load-balancing among phases).
特長

- Support automatic phase-shedding, PFM and LDO modes
- Simple 2-wire interface for device configuration, control, and status exchange to the host PMIC
- Automatic detection by Host PMIC
- No analog feedback to PMIC required
- Thermal limit warning flag and load current monitor capability optional
- Automatic load-balancing and heat re-distribution among phases optional
- Digital modulation and ML-based error correction
- Industrial temperature range of -40 °C to +85 °C
- 12-lead 3mm x 4mm DFN (NRG12)
