Tool/software:
Hello expert ,
we used LM61440AASQRJRRQ1 in our project , currently we tested the loop stability of this circuit , as the load is disabled so we test at light load (current =0A) the result is failed the output voltage is OK.
here is our circuit and the test results ;
can you help review the schematic and give your advice ?
if we need to adjust the value of Rff and Cff, is there any guide document and formula . many thanks
