Other Parts Discussed in Thread: CSD18512Q5B, , LM5148-LM25148DESIGN-CALC
Hi
Using this part in power designer with the following design criteria:
20-28V Vin
12V Vout
4A Iout
125DegC operating
This will suggest for instance FET
https://www.digikey.com/en/products/detail/texas-instruments/CSD18533Q5A/3674878
However I cannot find ANY of the suggested parts stocked at TI/Digikey
I did find this one though
https://www.digikey.com/en/products/detail/texas-instruments/CSD18512Q5BT/7312657
Key differences are:
60V at suggested device vs 40V at the device I found
100A Tc at suggested device vs 211A Tc at device I found
5.9mOhm Rds on at suggested device vs 1.6mOhm at device I found
116W Tc at suggested device vs 139W Tc at device I dound
+ some other differences.
I'm not a DCDC designer normally, but would the device I identified work fine? Not sure what the design criteria to look for are here
Thanks in advance!
