PD24

PD输入24V(可调输出)升压输出模块

原理图

简单来说就是使用HUSB238诱骗PD输出20V(诱骗不到20V就以此往下诱骗,最低5V)的电压,CSD25402Q3A过流控制,然后通过MT3608升压到24V输出

哪怕完全不支持PD,也可以输出24V,不过能够提供的功率就比较有限了

保留了数控接口,可以将PD24的输入电压和总线上的电流电压传给PD24_ctrl模块,计划通过INA226读取,并在OLED上显示

实物焊接

因为没有开钢网,所以这些都是用烙铁上锡后用加热台焊接的,经常容易把控不住锡量,焊接比较难看,但是不影响功能

后话

这个模块一开始的时候因为电感没有到,所以我就直接焊上去用,结果MT3608和电感一下子就烧了,现在想想可能是因为没有焊接输出电容的原因,导致芯片震荡,最终烧掉
