AI Technical Summary
Technical Problem
[0003]以往平台CPU供电使用的数字电源芯片寄存器内资料刷新速度较慢(60秒以上)，且刷新次数受限(8或28次等)，当芯片达到资料刷新次数上限后，若还需要更新芯片资料，必须重新更换芯片本体硬件方可完成，影响Debug调试效率，增加主板因更换芯片导致主板损坏风险；且电源芯片支持的平台较为单一，方案兼容性较差，利用率较低，升级新平台需要重新开发方案才能完成，增加开发频率及研发成本
Benefits of technology
[0015]本实用新型实施例提供的技术方案中，所述控制器包括至少一个电源模块，所述数字电源芯片包括寄存器，所述寄存器存储有对应于电源模块的各电源参数，所述驱动电路一端连接数字电源芯片，另一端通过滤波电路连接控制器，所述数字电源芯片通过驱动电路给控制器提供工作电源，本申请数字电源芯片内部寄存器寄存资料刷新较快，刷新次数不受限制，便于调试和维修，本电路兼容性强，支持平台应用范围更广泛。
