摘　　要：利用单片式开关稳压器LM2576 ADJ构成Buck变换器,不稳定直流电压仍采用线性电源方法获得,输出直流电压既保持了线性电源宽范围连续可调的特点,又具有开关电源高效率的优点,电路简单,实用性强。A buck convertor is consists of LM2576-ADJ of single-chip switching voltage stabilize. In this convertor , instability DC voltage is still obtained by liner power supply and output DC voltage is not only a wide range of continuous and adjustable characteristic but is feature of high efficiency . The convertor is simple and strong useful.
