Circuit Diagram =link=: Tl494

The IC uses an error amplifier to adjust the output voltage relative to the load, providing consistent output current, say, in a buck converter scenario.

Versatile enough for many topologies. The Basic TL494 Circuit Diagram tl494 circuit diagram

The oscillator generates a sawtooth wave. The PWM comparator compares this sawtooth with control signals (from error amps or feedback). The result is a variable-width pulse train that drives the output transistors. The IC uses an error amplifier to adjust
