Which resistor should I add in place of potentiometer in XL6009 boost converter module to increase 3.7 V to 12 V?

I'm using 18650 batteries with XL6009 boost converter module to increase 3.7 V to 12 V. There is a potentiometer to control the output voltage in boost converter. But can we fix the output voltage to 12 V using resistor in place of potentiometer?

  • According to datasheetspdf.com the feedback pin of the XL6009 works at 1.25V

    so you'll need a pair of resistors that can make 1.25V from 12V

    so from the hole for the middle pot pin 1K to 0V and 8.6K (from the same starting place) to the output voltage.
