This circuit is about a buck regulator which can produce an output of 5V for a input voltage ranging from 7V to 40V. LM2576 is a monolithic IC and it acts as the heart of this circuit. This IC has a potential of delivering an output current up to 3A and requires less number of external components. It is highly efficient when compared to other three terminal linear regulators and small in size.
