如何连接CCG3PA中的SWD_DAT,SWD_CLK,AXRES,FB引脚?

我用CG3PA芯片设计手机充电器。输入将是一个大约5V的电机电源,预期输出也将是大约5V。我在数据表中设计了类似于图7的示意图,并且我遇到了以下问题:
1。如果我用16针代替24针好吗?
2。我应该如何连接FB引脚,如果我的输入是5V已经与分压器?
三。数据表提到,我需要一个编程硬件,但我不需要数据传输为我的目的,这对我来说是必要的吗?另外,如果需要的话,我应该如何连接SWDYDAT、SWDY-CLK和AxRes?
谢谢

  I am designing a mobile phone charger using CCG3PA chip. The input will be a motor power supplies about 5V and expected output would be about 5V too. I have designed the schematic similar to Figure 7 in the datasheet, and I have encountered the following questions:
1. Would it be fine if I use 16-pin instead of the 24 pins?
2.  How should I connect FB pin if my input is 5V already with out the voltage divider?
3.  The datasheet mentioned that I would need a programming hardware, but I do not need data transfer for my purpose, would this be necessary for me? Also, how should I connect SWD_DAT, SWD_CLK, and AXRES if I would need it?
Thanks

你好智和赖,
请参考以下评论:
1。如果我用16针代替24针好吗?

我不明白,所以让我进一步澄清我的问题:
当你说“浮动”的FB引脚,你的意思是连接到地面或
输入电压?
至于编程引脚去,我不知道它是用来做什么。如果我
不要使用它们(直接研磨它们),芯片会工作吗?即供应
电源C型插座。
而且,我知道我用24针画了一张照片,但是我打算用16个。
引脚芯片。
谢谢

  I didn't understand that, so let me clarify my question further:
when you said "float" the FB pin, did you mean connect it to ground or to
input voltage?
As far as the programming pins go, I am not sure what it's used for. If I
don't use them (ground them directly), will the chip work? i.e. supplying
power to the type-c receptacle.
Also, I know I put up a picture with 24 pins, but I am intending to use 16
pins chip.
Thanks
