problem controlling variable DC-DC LTC1261LCS8-4
« on: April 14, 2024, 08:58:42 am »
Hello,In the datasheet shown below they say that the output resistance could be controlled using the COMP pin as shown in the links below.
I have tried to simulate this component in LTSPICE.
However I cannot understand the datasheet regarding how exactly do I need to use the COMP pin for tuning the output voltage?
LTSPICE  and phots are attached in the link.( I dont know other ways to present here photos and simulation files :-)
Thanks.

Your part is not adjustable, it seems..
The Adjustable parts should not end with the suffix -4 or -4.5..
