Hi all ,

I am working on Li-ion battery charger and I have gone through the one of manual of 2KW Lead-acid/Li-ion battery charger.

I attached the link for the same. Following are some of my queries regarding the same.

1. I want all the magnetic data such as PFC inductor, LLC inductor, main transformer and biased supply transformer how can I get this.

I tries to add the pdf file but there is some tricky so I could not.'

2. When I was looking into the schematic they have used NT1,NT2.....and so on. I tried to find out about these notations I could not find and explanation for the same.

Please help me to sort this out. What are these notations means ???

Waiting for your valuable reply..

Thanks..

Hi.Infineon

目前使用CCG3 PA  CYPD3171做的power bank，跟大部分设备充电都能做try source,但当碰到 yoga 14S笔记本时，发现反向充电故障（笔记本给充电宝充，充电宝电量是75%；笔记本电量 30% 之间）。不断插拔C口，10次，有6次出现反冲。问下：3171在power bank上做try souce是否有优先等级的设置，比如设置成1是最高，8是最低呢？从沟通日志来看，没有看到角色切换动作，power bank直接就做成了sink。
