### **Descriptions:**  
The TL494CN is a PWM controller IC designed for switch-mode power supply control. It provides adjustable frequency and duty cycle control, making it suitable for various DC-DC converter topologies. It includes an on-chip oscillator, error amplifiers, a dead-time control comparator, and output control logic.  

### **Features:**  
- Complete PWM power control circuitry  
- Adjustable dead-time control  
- Internal oscillator with frequency programmability  
- Uncommitted output transistors (200mA sink/source)  
- Dual error amplifiers for feedback control  
- Push-pull or single-ended output operation  
- Under-voltage lockout (UVLO) protection  
- Internal reference voltage (5V ±1%)  

This information is strictly based on the technical specifications and features of the TL494CN as provided in Ic-phoenix technical data files. No additional suggestions or guidance are included.

Application Scenarios & Design Considerations

SMPS Controller

Alternative Part Number

  • KA7500B --: Pin-compatible PWM controller with nearly identical function and specifications to TL494, widely used as a direct substitute in switching power supplies.
  • SG3524N --: Classic PWM regulator IC with similar control architecture and DIP-16 package, suitable for many TL494 applications with minor circuit adjustments.
  • UC3846N --: Current-mode PWM controller offering comparable drive and regulation features, usable as an alternative in power supply designs when layout and compensation are adapted.
