    How much is the current where burst mode is turned on for LTM4632?
    Rough value will be fine.
      VIN : 3.3V
      VOUT: 1.2V

    Hello,
    

    

    This is not possible as the minimum input voltage of the part is 3.6V
    

     
    

    

    Regards,

      Hi Jhun.
      

      Thank you for replying.
      

      Sorry, I was wrong. Vin is 12V.
      

      So, I'd like you to reply regarding the current in burst mode.

      You did not provide any specification about the load. My advice would be try simulating it through LTSpice to get an idea on what to expect about your design.
