Tl494 Circuit Diagram ((hot)) -

: This "Output Control" pin determines the operation; grounding it enables single-ended output, while connecting it to the 5V reference enables push-pull mode.

Example: 12V→5V, 3A, f_osc=50kHz, ΔI_L=1A L = (12‑5)×(5/12) / (1×50000) ≈ 58µH C_out = 1 / (8×50000×0.050V) ≈ 50µF (use low‑ESR, e.g., 220µF+ ceramic) tl494 circuit diagram

The TL494 has two output transistors, which can sink or source up to 200mA, generally requiring an external totem pole gate drive for controlling power MOSFETs effectively. : This "Output Control" pin determines the operation;

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. grounding it enables single-ended output
