hi to every one ....
i want to design buck converter and my requirement is to convert 24v to 14v . first calculate the values for inductor and capacitors from formulas given by microchip .and now i am checking it in proteus but my required result is not obtained. please help me it is my smester project i will be thanks full for u..the diagram of simulation is given below.

 

thank you sir . it has fix my problem . before connecting load my output was 23.8 giving input 24v.and now 9.92v is output giving input 24v. but there is still problem, that is i need 14v out and in this circuit my output is 9.92v.
i have changged the value of inductor and duty cycle very drasticaly but no effect..please help me...
thanks alot ..
 

Hi,

maybe you don´t drive the FET correctely. We can´t verify it. What is the setup?

The gate voltage should be referenced to source. I assume level 0V / 10V. Read datasheet.

Scope pictures of gate voltage and source voltage could clarify things.
