My ciruit:
problem ciruit

Input: 3.7V
But no matter how I adjust the potentiometer, the voltage did not rise.
How can I solve it?

The most obvious problem is that the enable pin (EN) is floating. Try connecting it to Vin as per the data sheet: -

Other potential issues?

  • Why haven't you got 220 uF on the output like the data sheet suggests?
  • What output voltage are you trying to achieve?
  • What is SW1 all about?
  • Why haven't you got the recommended input capacitance?
