What is the advantage of monolithic switching regulators?

What is the advantage of monolithic switching regulators?
by

1 Answer

Answer :

*Greater efficiency is achieved as the power transistor is made to operate as low impedance switch.Power transmitted across the transistor is in discrete pulses rather than as a steady current flow. *By using suitable switching loss reduction technique, the switching frequency can be increased so as to reduce the size and weight of the inductors and capacitors
