Part Number: LM5161-Q1
We got a question from the customer about LM5161-Q1.Could you help us?
[Question]How much is the variation of the constant 1.008*10^(-10) under the following condition?
Topology: Inverting Buck-Boost Vin: 6~32V, 6~20V Vout: 8V
They are concerned about reaching the current limit due to the variation of ton. Therefore they need this to estimate ton.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Hi, Thank you for your reply.
They are concerned about the inductor current hits the current limit. The ton varies by the IC at one condtion. For example, IC-A has short ton which the inductor current doesn't hit the current limit, but IC-B has long ton which makes the current limit condition.
We assume we can estimate the variation from the datasheet section 6.6. But it seems to depend on VIN condition and becomes worse as the input voltage increases. Therefore they want to make sure the variation at their own condition. Could you provide the variation of the constant 1.008*10^(-10)? We don't need guarantee. They will use it as reference.

Hi, There was typo on previous post. Vout is -8V. I corrected that and inform you.
Hi, Is there any update on that. If you need more information for this, I could send it by e-mail. Could you provide your e-mail address?
I would appreciate it, if you could give us your feedback.
