LM5175: voltage range in Buck/Boost/Buck-Boost mode

$

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
