Part Number: TPS53915

Hi,

Could you tell me about TPS53915 internal Rvrm and Lvrm spec?
Customers want that information for Altera's PLD tool.
Could you give me a reference value for entering into the tool?
I understand this value as information based on the internal error amplifier.

I will describe the tool information below.

I do not see any reference to those terms in the datasheet. The linked document is rather long. I do not have the BW to study it in detail. Can you describe to me what you are looking for?

John-san,

Thank you for your response.
Customers want ESR and ESL information inside the device.
Becouse,Customer needs to input the output impedance information to the simulation tool.
(Enpirion has modeled this information.)

Could you give me your advice?

Best Regards,

Are they looking for just the device, or the converter circuit? What model type is this? Is it IBIS?
