摘要
文章以芯片TPS5430为核心构成DC-DC变换器,由51单片机组成测控电路,通过单元电路上的按键改变占空比来调节输出电压,辅助电源由直流稳压电源经过稳压芯片L7805CV输出5 V电源。整个系统充分利用了TPS5430过流保护和热关断功能,性能测试较为完善,比较好地实现了设计要求。
In this paper, the DC-DC converter is composed by the core TPS5430 chip. It is composed of 51 single-chip microcomputer control circuit, which regulates the output voltage by changing the duty cycle through the buttons on the circuit unit. The auxiliary power outputs 5V power supplying from the DC power through the voltage chip L7805CV. The whole system makes full use of TPS5430 over- current protection and thermal shutdown function, the performance test is perfect and meets the design requirements.
