Description and Introduction

Dual Channel Controller with Wide Input Voltage Range The TL1451ACNSR is a dual pulse-width modulation (PWM) controller manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **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 40V  
- **Output Current:** 200mA (sink/source per channel)  
- **Switching Frequency:** Adjustable up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Gain Bandwidth:** 1MHz  
- **Reference Voltage:** 2.5V ±1%  

### **Descriptions:**  
The TL1451ACNSR is a dual PWM control circuit designed for power supply and DC-DC converter applications. It features two independent PWM controllers, each with an error amplifier, a comparator, and an oscillator. The device operates over a wide input voltage range and provides adjustable frequency and duty cycle control.  

### **Features:**  
- **Dual PWM Control:** Independent control for two channels.  
- **Wide Input Voltage Range:** 3.6V to 40V.  
- **Adjustable Frequency:** Up to 500kHz.  
- **Precision Reference Voltage:** 2.5V ±1% accuracy.  
- **Error Amplifiers:** High-gain bandwidth for stable feedback control.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Short-Circuit Protection:** Improves system reliability.
