| Abstract: | The design of power supply module is very pivotal,because it influences the system realizing and running in the video frequency compress system.The paper introduces a viable design project of supply power,as MAP-CA. It can make the core pressure of MAP-CA taking precedence of I/O.Then it can assure logical gradation of supply power.It can assure the system running safely and stably by the supervising circuit of pressure,too. |
