I am using TPS65265 with Vin=12V to get triple output voltage of 3.3V, 5V and 3.7V. Help me in choosing DC-DC loop compensation values for each of the output channel. schematic of same is attached.TPS65265.pdf

Hi,
I think is as same as below link. Because you use the same schematic. I have responded to below thread and will close this one. Thanks.

Hi Radhika,
For inductors and compensations, my suggestions are shown below:
1. Change R23 to 21kohm (customers can choose similar values);
2. Change R29 to 16.4kohm, change C54 to 4.7nF;
3. Change R33 to 12kohm, change C60 to 6.8nF;
4. Change L3 to 5.6uH or 6.8uH;
5. Change L4 to 6.8uH or 8.2uH.
No other obvious problems. Thanks.
Aurora
