LM63625-Q1: Request for Line and Load Regulation Data at 400 kHz

The-Tiep Pham

Part Number: LM63625-Q1

Tool/software:

Hi,

My customer has asked about the accuracy of the 5 V output of this IC. Currently, we are operating at a switching frequency of 400 kHz. However, the line and load regulation at this frequency is not provided in the datasheet.

Could you please provide a graph similar to Figure 8-16 (shown below) and some explanations but corresponding to a 400 kHz switching frequency?

Thank you very much for your support and hope to hear you soon.

Best regards,
The-Tiep Pham.

Hello

The line/load regulation will not be different for a 400kHz design.

The exact load point at which the regulator changes to PFM mode will change.

However, the maximum and minimum output voltage range will not change.

Thanks

Dear Mr. Frank,

Thank you for your response. This has resolved my issue.

However, if you could kindly provide any tested results or data related to this topic, it would serve as strong evidence to support my explanation to the customer.

I appreciate your assistance and look forward to your reply.

Best regards,
The-Tiep Pham.
