Tl494 - Circuit Diagram

Adjusting the potentiometer changes the duty cycle from ~0% to ~95%.

Used in modified sine wave inverters:

| Application | Configuration | |-------------|---------------| | Boost converter | Single-ended, external MOSFET | | Push-pull inverter | Pin 13 to REF, external transformers | | Battery charger | Use second error amp for current limiting | | Solar MPPT controller | Dual-loop control using both error amps | | ATX power supply modification | Replace original PWM controller | tl494 circuit diagram
