Description and Introduction

DUAL PULSE-WIDTH-MODULATION CONTROL CIRCUIT The TL1451ACNSLE is a dual pulse-width modulation (PWM) controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** Dual PWM Controller  
- **Package:** SOIC-16  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** 3.6V to 50V  
- **Output Current (Sink/Source):** 200mA (per channel)  
- **Switching Frequency:** Adjustable up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Number of Channels:** 2  
- **Error Amplifier Bandwidth:** 1MHz (typical)  

### **Descriptions:**
- The TL1451ACNSLE is a dual PWM control circuit designed for DC-DC converter applications.  
- It includes two independent PWM controllers with error amplifiers, adjustable dead-time control, and an internal voltage reference.  
- Suitable for push-pull, half-bridge, and full-bridge power supply designs.  

### **Features:**
1. **Dual PWM Controllers:** Two independent control channels.  
2. **Wide Input Voltage Range:** Operates from 3.6V to 50V.  
3. **Adjustable Dead-Time Control:** Prevents shoot-through in bridge circuits.  
4. **Internal Voltage Reference:** 2.5V ±1% precision reference.  
5. **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
6. **Short-Circuit Protection:** Includes pulse-by-pulse current limiting.  
7. **Synchronizable Oscillator:** Allows synchronization with external clock signals.  
8. **Low Standby Current:** Typically 1.6mA.  

This information is based solely on the manufacturer's datasheet for the TL1451ACNSLE.
