Check the voltage on Pin 4 (DTC). If it is shorted directly to ground, the dead-time is zero. This causes cross-conduction shoot-through currents. Unstable Output Frequency: Inspect the capacitor on Pin 5 ( CTcap C sub cap T ) and the resistor on Pin 6 ( RTcap R sub cap T tl494 circuit diagram

The TL494 uses a standard 16-pin dual-in-line package (DIP-16) or surface-mount (SOIC) layout. Each pin plays a crucial role in controlling the duty cycle and monitoring safety parameters. Pin Number Description IN+ (Error Amp 1) +---U---+ 1IN+ -| 1 16 |- 2IN- 1IN-
