摘要
针对电源要满足高精度,高可靠性以及低功耗等实际工况,设计了一种高精度的开关电源,保证输出电压的稳定、高精度以及低功耗.该设计在分析了Buck拓扑结构电路的基础上,对该拓扑电路核心器件电感的波形进行分析,然后以电感为核心用分立元器件搭建电路.该设计满足低功耗、低纹波率的设计要求,同时,能够保证输出电压的稳定.
In order to meet the practical conditions of high precision,high reliability and low power consumption,a high precision switching power supply was designed to ensure the stability of output voltage,high precision and low power consumption.Based on the Buck topology circuit,the waveform of the inductor was analyzed as the core device of the topology circuit.With the inductor as the core,the circuit was constructed with discrete components.The design meets the design requirements of low power consumption and low ripple rate,while ensuring the stability of the output voltage.
