TPS54295 Power dissipation and Input current information needed

Other Parts Discussed in Thread: TPS54295, TPS54260

Hi,

Customer of mine is designing their power stage using dual channel DCDC – TPS54295 and TPS54260. Please see the attached diagram for details.

I’ve few questions:

- Could you advise the Pd, temperature, input current on the dual channel DCDC (TPS54295) circuit. I’ve tried to simulate TPS54295 using SwitcherPro but only limited information available in the SwitcherPro.

- Referring to the pg2 in the attachment, could you advise why the converter showing the max temp of 35 only? Does it mean this converter dissipate power of 764mW @ 35 degree?

I’ve also attached the schematic for both TPS54260 and TPS54295 for your reference.

Thanks
