Part Number:UCC27211A
Dear:
The capacitance of the bootstrap in my client's application solution is between 1uF and 2.2uF, which affects the current during forward conduction of the bootstrap. I would like to ask what is the maximum forward current that this bootstrap can withstand. I don't see this parameter marked on the SPEC,please help me answer this question,thanks very much。

Hi
datasheet没有这个规格,但是一般不建议太大,可以串联一个1~2ohm的电阻。

请问一下不建议太大,有个推荐的范围么?bootdiode设计是内置的,正向导通的时没有一个最大的电流设计指标么?

Hi
个人推荐不超过6A, 之前看到一些有较大电流的情况,都是由串联一个小电阻的.
