Part Number:LM22675
Hello.
I use LM22675 with the following specification.
Specification
Vin: 21.6~25.1V (TYP=24V)
Vout: 10V
Iout: 1A
There is the following description on page 8 of SNVS591L.
"If an output voltage of 5V or greater is required,
the -5.0 option can be used with an external voltage divider."
However, the output voltage is larger than 10V when I use LM22675MRX-5.0.
I think this reason is FB resistance of 9.93kohm in LM22675MRX-5.0.
5V/9.93kohm=500uA
There is the following description on page 13 of SNVS591L.
"For the -5.0 option, the total internal divider resistance is typically 9.93 kΩ."
I heard that I had better use LM22675MRX-ADJ for reason of the above when the output voltage is more than 5V.
This is the thing which I heard in 2009.
I heard that the data sheet will be revised, but it has not been yet revised.
In the case of the above (Vout=10V), is it correct to use LM22675MRX-ADJ?
