Description and Introduction

DUAL PULSE-WIDTH-MODULATION CONTROL CIRCUITS The TL1451ACDB is a 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 Current (Sink/Source):** 200mA (per output)  
- **Switching Frequency:** Up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Gain Bandwidth:** 1MHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Description:**  
The TL1451ACDB is a dual PWM controller designed for DC-DC converter applications. It includes two independent control circuits, each with an error amplifier, PWM comparator, and an output driver. It is commonly used in power supply designs, battery chargers, and voltage regulators.  

### **Features:**  
- Dual PWM control channels  
- Adjustable dead-time control  
- Internal undervoltage lockout (UVLO)  
- On-chip error amplifiers  
- Soft-start capability  
- Synchronizable oscillator  
- Short-circuit protection  

This device is optimized for high-efficiency power conversion applications.
