Description and Introduction

Dual Channel Controller with Wide Input Voltage Range The TL1451ACD is a dual pulse-width modulation (PWM) control circuit manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage (VCC):** 3.6V to 40V  
- **Output Voltage:** Up to 40V  
- **Output Current (Sink/Source):** 200mA (per channel)  
- **Oscillator Frequency Range:** 1kHz to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Descriptions:**
- The TL1451ACD is a dual-channel PWM controller designed for DC-DC converter applications.  
- It includes two independent error amplifiers, an adjustable oscillator, dead-time control, and PWM comparators.  
- Suitable for push-pull, flyback, and buck/boost converter topologies.  

### **Features:**
- **Dual PWM Control:** Two independent control channels.  
- **Adjustable Dead Time:** Prevents shoot-through in half-bridge applications.  
- **Error Amplifiers:** High-gain bandwidth for precise regulation.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Internal Reference Voltage:** 2.5V ±1% accuracy.
