LM5022: BOOST CONVERTER DESIGN - CHANGING / GETTING DESIRED OUTPUT - REG

Hi Subash,

Thank you for using E2E forums, regarding your query the FB voltage divider is not set to the right values in order for you to get 24V output. According to my calculation with the current set up you will get around 27V to 26V output. Maybe check your FB voltage divider circuit? The FB voltage reference is 1.25V on average so I would recalculate the FB divider circuit.

Thank you

@haroon, Thanks for the reply. What should be the voltage at the FB pin.? what changes the output? is it RT resistor? or Comp resistor and capacitors? 

Hi Subash,

The Vout is changed by changing the FB divider circuit, the upper resistor and the lower resistor that makes the voltage divider and based on the resistance values and the fact that the FB pin will have 1.25V on average you can calculate the Vout.
