Part Number: LM25119Q

Dear, Sir.

My customer is considering to change fSW  130kHz <=> 300kHz under the operation.

It is expected to reduce the influence of minimum On-time to set at lower fSW.

1. I would like to know that such usage will be no problem.

2. If above is no problem, Please let me know what will be concering or bottle-neck point.

Best Regards,

H. Sakai
