Here is a simple Electronic Circuit Project of DC-DC regulating converter circuit. Push-pull outputs are used in this transformer-coupled dc-dc regulating converter.
DC-DC Regulating Converter Circuit Diagram:
Note that the oscillator must be set at twice the desired output frequency as the SGI 524`s internal flip-flop divides the frequency by 2 as it switches the PWM signal from one output to the other Current limiting is done here in the primary so that the pulse width will be reduced should transformer saturation occur.
