- **Mounting Type:** Surface Mount  

### **Descriptions:**  
The TL1451ACDBRG4 is a dual PWM control circuit designed primarily for DC-DC converter applications. It includes an on-chip oscillator, error amplifiers, adjustable dead-time control, and PWM comparators. It is suitable for push-pull, half-bridge, and flyback converter topologies.  

### **Features:**  
- **Dual PWM Control:** Two independent PWM channels.  
- **Wide Input Voltage Range:** 3.6V to 40V.  
- **Adjustable Dead-Time Control:** Prevents shoot-through in half-bridge applications.  
- **On-Chip Oscillator:** Programmable frequency via external components.  
- **Error Amplifiers:** Provides precise voltage regulation.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Short-Circuit Protection:** Enhances system reliability.  
- **SOIC-16 Package:** Compact surface-mount design.  

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