Part Number: LM5143DESIGN-CALC Other Parts Discussed in Thread: LM5143 Hello Team,
Can i get the password to unlock the LM5143 Design Calculator. We would like to access each individual cell so that a macro can be written to manipulate the cells from…

2Ch Output Voltage : 12.5V
2Ch Output Current : Max 30A ( Typ 25~27A …
Hello,
There is no input "setpoint" - the whole purpose of a buck regulator is to take a variable input voltage and convert it to a fixed output voltage. Sure, you can have a nominal Vin, which is 12V in your case. Please use the LM5143 quickstart calculator…
Part Number: LM5143DESIGN-CALC Other Parts Discussed in Thread: LM5143-Q1 , LM5145 Hi team,
here is two confusing items of LM5143q design:
1.there is a descripton as following in the datasheet what seems not to make sense, actually it suppose that there…
Hello,
You can use the LM25143-Q1 42V input version of the controller here. As it's a controller, the applicable application space is quite broad.
My recommendation is to use the quickstart calculator to assist with your design: https://www.ti.com…
Hi Darshan,
Qoss is the area under the Coss vs. Vds curve at a given voltage and is sometimes given by the FET vendor in the data sheet. Eoss is not typically provided for Si FETs (more for GaN), so you may want to ask the FET vendor. In any event, you…
Hello Anbarasan,
please can you fill out the design calculator inserting VOUT mx at your VOUT so we can check design against your spec requirements. . Please note it's a public Holiday today so responses will be somewhat delayed.

Hi Shelly,
You can use the LM(2)5143 quickstart calculator to assist with compensation design: https://www.ti.com/tool/LM5143DESIGN-CALC . Just ensure that the value for ceramic Cout is derated for voltage
Ccomp controls the compensator zero location…
Parker,
Go ahead and fill out the quickstart calculator and I will review it for each design. See the apps circuit examples in the datasheet for reference. Btw, the LM5137-Q1 is online now.
