TPS55332EVM: How we calculate C10 and R10 value for loop stability? Part Number: TPS55332EVM Hi team, Could you tell me how we calculate and modify C10 and R10 value for loop stability in TPS55332EVM datasheet? I added large input capacitor (for Vbat) and large output capacitor (for Vout). Then TPS55332EVM does not work and COMP pin oscillated. I guess it is due to loop stability. Regards, Ochi Hi Ochi-san, I notify our expert who is in a different time zone where is already the weekend now. The datasheet gives instruction of these component selection in section 8.2.2.8, in which C8 corresponds to C10 of the EVM. R10 is to introduce additional zero but it seems not needed according to datasheet discussion on the example design. Hope this clarifies. Thanks, Youhao Xi, Applications Engineering Hello Xi, Could you please explain how we use/understand below figure? I am lack of knowledge for pole, zero, and compensation circuit. Could you give me training resources for them? Regards, Ochi Hi Ochi-san, There iscompany online training course at the following link. /control-smps-loop-transfer-functions?keyMatch=LOOP%20COMPENSATION&tisearch=Search-EN-everything You may also refer to a control theory text book to get some fundamental theory.
