### **Descriptions:**  
The TL494CDRG4 is a fixed-frequency PWM controller designed for switch-mode power supply applications. It provides push-pull or single-ended output control, adjustable dead-time control, and an on-chip oscillator. It is widely used in DC-DC converters, inverters, and power regulation circuits.  

### **Features:**  
- Complete PWM control circuitry  
- Adjustable dead-time control  
- On-chip error amplifier  
- On-chip 5V reference regulator (±1% accuracy)  
- Uncommitted output transistors (200mA sink/source)  
- Output control for push-pull or single-ended operation  
- Undervoltage lockout (UVLO)  
- Internal oscillator with frequency programmability  

This information is based on the manufacturer's datasheet and product specifications.
