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.
What are you targeting for your power supply?
Tied directly to GND (Pin 7) . This disables the toggling flip-flop, allowing both transistors to turn on and off at the exact same time. tl494 circuit diagram
Understanding these circuit topologies allows you to build efficient power supplies, inverters, and chargers from datasheet reference designs.
Sets the minimum blanking period between output pulses to prevent cross-conduction in push-pull topologies. The IC uses an error amplifier to adjust
