Description and Introduction

Dual Channel Controller with Wide Input Voltage Range The TL1451ACDBR is a pulse-width modulation (PWM) controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage (VCC):** 3.6V to 50V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Current (Sink/Source):** 200mA (per channel)  
- **Switching Frequency:** Up to 500kHz  
- **Number of Outputs:** 2 (Dual PWM Controller)  
- **Package:** SOIC-16  

### **Descriptions:**
- The TL1451ACDBR is a dual PWM controller designed for DC-DC converter applications.  
- It features two independent error amplifiers, an adjustable oscillator, dead-time control, and a precision reference.  
- Suitable for push-pull, flyback, and boost/buck converter topologies.  

### **Features:**
- **Dual PWM Control:** Independent control for two outputs.  
- **Adjustable Dead Time:** Prevents shoot-through in half-bridge applications.  
- **Internal Reference Voltage:** 2.5V ±1% accuracy.  
- **Error Amplifiers:** Wide common-mode range for feedback control.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low supply conditions.  
- **Synchronization Capability:** Allows external clock synchronization.  

The TL1451ACDBR is commonly used in power supply designs, including industrial and automotive applications.
