Dears currently used TPS61096A for variable output application through switching dedicated resister divider using external - mosfet ,
so couly you help check below parameter may related with my application
1. Vosns - output voltage sense pin + FB , monitor from my oscilloscope , it seems that 10us duration and FB ping should be sample during this period .
could you support us the detail logic of Vosns on time combine with FB sampling .
2. below is my sch, and prepare to use mosfet configure the ouput , but the mosfet intenal c influnce the procedure of FB sampling which lead to some mis-voltage output,
could you give us some golden adivise, really looking forward to your reply.

Hi Nicky,
what is the value of all the feedback resistors value? could you use smaller value resistor and smaller capacitance MOSFET?
what is your application an why did you use this device.
Hi Nicky,
did you try lower resistor, such as 34k+10k. why did you select this device for your application?
