TPS62130: Circuit verification

yoo young jae
Prodigy 120 points
Part Number: TPS62130
Other Parts Discussed in Thread: TPS62135

hello

We will use the output as shown below.

Input=14V(DC)

Output= 3.3V(3A),2.5(3A),1.8V(3A),1.25V(3A),1.2V(3A)

 1. Are you having trouble changing only the FB?

 2. Is it a problem-free circuit?

 3. If there is a problematic circuit, which part should I change?

4. Request circuit verification

    Hi Yoo,

    I don't quite understand your questions, but this circuit looks mostly ok. I would recommend removing some of the output capacitance, as it is already above the range shown in the D/S. There is likely additional capacitance located at the load, which must also be accounted for.

    Finally, we have the newer, smaller, more accurate, higher current TPS62135/6 which are recommended.
