Other Parts Discussed in Thread: LM5168-Q1, LM34927
I have a customer who is interested in using LM5169-Q1 and were curious about the current limit.
From the data sheet, it mentions that the current limit is 0.7A while LM5168-Q1 is 0.35A, but both model have same high side or low side mosfet Rds on as shown in the screenshot below:
May I kindly check with you if the datasheet is correct? I think if we double the current, the resistance should become a quarter in order to make the same conduction loss.
I compare with older model LM34927, that have same current limit : 0.7A, LM34927 high side and low side mosfet Rds on are around half LM5169-Q1 specifications, please see below:
Please help to verify about this.
