aside from choosing a low resistance inductor wouldn't ganging diodes increase dc regulator efficiency simply because the I-V curves are exponential?

 

hi pager.
I see that you are a Student, are these Homework assignments.?

aside from choosing a low resistance inductor wouldn't ganging diodes increase dc regulator efficiency simply because the I-V curves are exponential?

does a regulator with built in mosfets have greater efficiency over bjt regulators?

thank you.

Adding more components normally does not increase efficiency.
Can you give a circuit?

The internal MOSFets should be with smaller and low resistance traces. They can even be with a low resistance drain source channel, but thats device specific, not an efficiency factor.
