Other Parts Discussed in Thread: LM25143
Tool/software:
Hi,
I am using LM25143-Q1 for Super capacitor charging, operating in constant current (CC) mode with external error amplifier to charge the super capacitor.
Input voltage is 12.5V to 15.5V and output voltage will be set with maximum Duty cycle. The Maximum output current is 125A. I am using 4 phase buck design for meeting the requirement.
My question is, i am using a very high capacitance ie Ultra capacitor (around 200 Fared), so no other capacitor is used at the output except some low value ceramic capacitor to suppress high frequency noise.
so, how to do the compensation circuit design for this converter, i have put this capacitor value in calculator as output capacitor and it was not providing any results or recommendation.
Can you please provide some information on this.
Regards
Rayees K.E
