摘　　要：随着芯片制程工艺的快速发展,超大集成门电路的FPGA广泛应用于通信、医疗、航天、航空等领域。现代FPGA的供电电源尤其是核电压的供电设计要求非常高,且在负载电流快速变化的条件下仍需要满足非常高的输出电压精度。相比传统的模拟类电源控制芯片,数字控制的电源芯片具有方便的环路设计,输出电压控制精度高,兼具PMBus电源管理系统的优点。分析了XILINX公司当代主流高性能FPGA核电压的参数要求,用数字控制芯片UCD9248设计满足要求的POL电源。With the rapid development of chip processor,very lage scale integration of FPGA is widely used in communication,medical,aerospace,aviation and other fields.Modern FPGA power supply,especially core voltage power supply design requirements are very high,such as low output voltage,and fast load current varying conditions still need to meet very high output voltage accuracy.Compared with the traditional analog power supply control chip,the digital control power supply chip with convenient loop design,high precision output voltage control,both PMBus power management system advantages.In this paper,the parameter requirements of XILNX company’s contemporary mainstream high-performance FPGA core voltage are analyzed,and the POL power supply satisfying the requirements is designed with the digital control chip UCD9248.
