0V起调的可调直流稳压电源的设计

Design of DC regulator with adjustable output from 0V

利用降压稳压器芯片TPS54360进行改进,实现输出电压为0~10V可调的直流稳压电源电路.设计了电压反馈电路,克服了TPS54360芯片只能从0.8V起调的问题,并进行了实际测试.结果表明:负载调整率为14.5%,最大输出电流为3A,具有稳定连续的调节能力,并且最大输出功率能达到23.9 W.

This paper shows a design of DC regulator with adjustable output from 0 to 10 V based on TPS54360. The circuit of voltage feedback solves the problem that TPS54360 can not adjust from 0 V. By actual test, the design has stable output voltage,load regulation is 14. 5%,the maximum output current is 3 A,the ability of stability regulate continuous and maximum output power can reach 23. 9 W. The structure of circuit is simple and can be widely used in electronic design and control.
