Emitter and Collector pins of the second internal output transistor. Pin 12 (VCC): Positive supply voltage input.
Increase a lower voltage to a higher one (e.g., 12V to 24V).
Let me know if you need:
In a step-down converter, the TL494 monitors the output voltage via pin 1 and adjusts the duty cycle of the MOSFET to maintain the desired output, even with varying loads or input voltage. B. Push-Pull Inverter Circuit
Using the second error amplifier (pins 15 & 16), the TL494 can be configured to limit current (constant current) and, once a certain voltage is reached, switch to constant voltage (CV) to safely charge lead-acid or lithium batteries. 5.
