Switching Regulator L296 Power Supply
L296 is a high current switching regulator that can provide up to 4 ampere current and its output voltage range is from 5.1v to 50v. For more information concern its datasheet. Power supply current can be adjust by changing the value of P1 pot. P2 and P3 pots are used to vary the output voltage. C7-C10 capacitors are used for input voltage filtering whereas C2-C6 are for output voltage filtering purpose. Output voltage can be taken across X1-1 and X1-2 terminals or either X1-2 and X1-3 terminals. Note that the maximum input voltage of L296 is 50v so we have to step down ac voltage by using 50v 4amp or appropriate transformer. Don't forget to use heat sink for L296.
