| Output 3 | 0.88 V |
| IC revision | A |
Description
This reference design addresses Xilinx Versal adaptive compute acceleration platform (ACAP) requirements and consists of a power management integrated circuit (PMIC) for system rails plus a multiphase controller and power stages to support higher current processor loads. On-board dynamic loads on the critical outputs allow testing to Xilinx's demanding power requirements. PMP22165 along with the TPS53681 EVM is a tested solution offering performance with components to meet processor requirements for Versal’s most common use cases one and three.
Features
- 10-rail user-programmable TPS650861 PMIC for both system-level power and full design sequence management
- Full system power solution for Versal's most common use cases one and three
- Optimized power stage combination for peak efficiency of 92% on the VCCINT rail at the nominal output voltage
- On-board dynamic loads for more critical outputs
Typical applications
- ADAS domain controller
- High performance computing, Hardware accelerator
