The solution is simple we just add a 3 3v linear regulator ic like ld1117 with the 12v rail and it regulates the voltage down to 3 3v. The circuit for the buck regulator operates by varying the amount of time in which inductor receives energy from the source. The circuit diagram of a 5v buck regulator based on the lm2678ic is shown below.
The buck regulator produces a lower average output voltage than the dc source input voltage.
The working of a buck boost regulator is explained using the circuit diagram as shown in figure 1. 5v buck regulator circuit the ic lm2678 has more than 90 efficiency and also line regulation and outstanding load. Buck converter circuit many a times in the electronics world we find the need to reduce one dc voltage to a lower one. Uc3573 buck regulator pwm control ic typical application circuit for 12vdc input to 5vdc 1a output also.
