To build a superior circuit, you need to upgrade three critical areas: the feedback loop, the dead-time control, and the output drive stage.
Using industry-standard symbols and consistent naming from the TL494 datasheet ensures the design is professional and traceable. 3.

It includes over-current protection (shuts down if overloaded) and slope compensation (a 1k resistor from Pin 3 to the oscillator prevents subharmonic oscillation at duty cycles over 50%).
