regulated bulk converter

hi all,
how to design a closed loop regulated buck converter that can produce a variable output voltage of 0 ~ 10V and is able to supply up to 10A load current at any output voltage?

 

You may wish to post up any attempts you have made to this question, if you are expecting and help. You might also be advised for the benefit of those not in the know, state what a "closed loop regulated buck converter" is.

An LTC1775 with an external switch should be capable of doing the job. Get a copy of LTSpice for the complete circuit.

 

It's probably not a good idea to design one with such a wide output voltage range. Unless you have a compelling reason to do so. Switchers work best at the designed fixed output voltages.

Incidentally, I've never seen one with output that goes as low as 0V. If you think about it, it kind of makes sense.
