Thanks for the reply. This will be an open loop circuit, so I will connect the output to a multimeter and vary the function generator duty cycle (at the base of the transistor) till I get the disired voltage.Don't see how it could work. No circuitry to regulate to 10V.
Hi crutschow. I am going to implement this circuit just for the fun of testing a switching regulatorVery little increased efficiency is obtained when going from 12V to 10V with a switching regulator.
A linear regulator is 83% efficient for that conversion, so even using a 90% efficient switching regulator will only gain 7% efficiency or about 2W less dissipation.
And you'd be hard pressed to get 90% efficiency using a BJT emitter follower for the switch since it has a minimum drop of about 0.7V when conducting.
