Description

1、工作原理: 由于与大电流的内置电源开关,MC34063可以控制开关电流为1.5A,内部电路包括一个参考电压源变换器、振荡器、逻辑控制电路和开关晶体管。 参考电压源是一种带隙基准的温度补偿。振荡器的振荡频率由3个引脚的外部定时电容确定。该开关晶体管是由比较器的反向输入端和与振荡器连接的逻辑控制电路组成,并且具有一个上,并且由下一个脉冲组成,该脉冲与振荡器的输出同步。 2、功能描述:该模块主要实现对直流5V升压直流12V; 3、各功能模块的描述: enter image description here 4、焊接前的电路板与元件清单; enter image description here 5,焊接后的实物正反面图; enter image description hereenter image description hereenter image description here
