摘要
分析了CCD相机外部单路供电,并为实现多路DC/DC转换功能,提出了一种开关型稳压电源与线性稳压电源相结合的系统设计方案。分析了具有BOOST/BUCK功能的开关电源和线性稳压电源的工作特性,并结合CCD相机的整体设计要求,实现了相机电源的功耗低、发热量小、EMI干扰轻的设计目标,从而提升了CCD相机的整体性能。
Construction of CCD camera power supply is analyzed in this paper, that provides camera with a single power outside. In order to realize a function of multiple DC/DC converter, a solution of system design for a switch regulated power supply combined with linear regulated power supply is proposed. Working two characteristics of regulated power supply are analyzed, one is a switch regulated power supply to be provided with BOOST/BUCK, another is linear. Aiming at the design demands of a whole CCD camera, the performances of lower power, lower heat and lighter EMI in a camera power supply were realized. So the whole performance of CCD camera was increased.
