LM5161-Q1: The variation of ton

Part Number: LM5161-Q1


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

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.

Best Regards,
