Part Number: LM5140-Q1 Other Parts Discussed in Thread: PMP15032 , LM5143A-Q1 , LM5143 , LM5137-Q1 Tool/software: dears,
My customer is planning to use LM5140 as a buck converter for the application: Vin=24V, Vout=5V (max current 40A), they will combine…
Part Number: LM5140-Q1 Other Parts Discussed in Thread: PMP15032 , LM5143-Q1 , Hi Expect,
Check from PMP15032, when we design for single output, extra OP amplify circuit was necessary for current sharing on COMP1 to COMP2, right? is it mush have or…
Part Number: LM5140-Q1 Other Parts Discussed in Thread: PMP15032 , , PMP7282 , LM5116 , LMC555 , LM5119Q Hi Team,
As title, my customer inquired us about our power solution for an application with 24 Vin, 12Vout / 50A.
I proposed our LM5140-Q1 and…
Hi Sundy,
The tool could not find any non-isolated solutions with that high output power. It would require multi-phase converters to get a conversion at that power level.
A couple of similar examples are:

Hello,
Yes, this should be alright. The main concern with the PMP15032 is that the EN resistors are setting a turn on voltage of 15V instead of 12V. By redesigning this resistor divider, this device is capable of turning on at 12V.
Best Regards…
Hello Chen,
The Iout is a recommendation based on reasonable thermal design. To obtain 15V out at 45A is not impossible for a single phase/LM5117, however the thermal design could be quite challenging. I recommend using a dual phase approach, consider…
