LM5161-Q1: Current limit condition and Reliability

Part Number: LM5161-Q1

Hi,

We got a question from the customer about LM5161-Q1.
Could you help us?

[Question]
They found the primary side transformer current hit the current limit of the IC at the start-up. Please refer to attached file for the details. Are there any concerens about the reliability of the IC in this usage?

Their start-up time requirement is 4msec, so they want to keep the current start-up time. If you need more details of this, I could send it by e-mail. Could you provide your e-mail address?

Best Regards,
tateo
