Hi to all,

Can I find out from the experts reading my post on how to design a average current mode control PWM buck converter?

Thank you and I hope to hear from you soon.
 

i need to kinow what are the specifications of the power supply you are designing.
you can find good referenceson current mode supply design on notes by lloyd dixon which are freely avalable on the net.
visit the link below.

Hey

Check this out: https://www.ipes.ethz.ch/

By the way, please tell me more about your design, Vin and Vout.

I suggest that you use special ICs to control the switch. IGBT or Power MOS
 

I am designing a 5Vin, 3Vout average current mode control PWM non-sync buck converter. drawing up to 1A load current. The switch is external and I am using a PMOS power transistor.
 

you can use the LM2576......... other ICs also available but they required large amount of components resistors, cap, inductors

that is why i am recommanded it
