Hello PYTsai,

Thanks for your question. Are you trying to trim the Vout to different values? If yes, what is your nominal Vout and within which range would you like to trim it? Could you specify your Vin and the range for VFB?

Kind regards,

Elisabetta

What is the nominal Vout you want for your circuit ? 11.6V
Within which Vout range would you like to trim it? 8.3V~11.6V
The Vin range ? 9V~16V
The range for VFB? 0~5V

Hello,

Schematics looks ok to trim in this range, please take into consideration that you might want to change the 100kOhm resistor (R4) to trim more or less accurately.

Kind regards,
