Part Number:LM5175
Hi someone in charge,
My customer has a related question.
Could you please advise?
The customer'd like to know because he needs to estimate power dissipation, the Duty cycle is needed.
---
(1) What is the maximum duty at buck-mode and the minimum duty at boost-mode?
(2) Can you tell the changing ON duty from Step-down operation to Buck-boost operation,
when the input / output voltage difference is large enough (VIN > VOUT) and then decrease to low differential voltage?
(3)Can you tell the changing ON duty from Boost operation to Buck-boost operation,
when the input / output voltage difference is large enough (VIN < VOUT) and then decrease to low differential voltage?
(4)Are there a graph like attached figure, these information are helpful.
The customer is also considering LT8390,

I appreciate your great help in advance.
Best regards,
Shinichi
