Description and Introduction

Dual Channel Controller with Wide Input Voltage Range The TL1451ACN is a pulse-width modulation (PWM) controller manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** PWM Controller  
- **Package:** PDIP-16 (Plastic Dual In-Line Package)  
- **Operating Voltage Range:** 3.6V to 40V  
- **Output Voltage:** Adjustable  
- **Switching Frequency:** Up to 500kHz  
- **Number of Outputs:** Dual (2 independent PWM controllers)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The TL1451ACN is a dual PWM controller designed for DC-DC converter applications.  
- It provides two independent control channels, each with error amplifiers, a PWM comparator, and an output driver.  
- Suitable for power supply designs, including step-up (boost), step-down (buck), and inverter configurations.  
- Features internal soft-start functionality to reduce inrush current.  

### **Features:**
- **Dual PWM Control:** Two independent channels for flexible power supply designs.  
- **Wide Input Voltage Range:** Supports 3.6V to 40V operation.  
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Error Amplifiers:** Built-in for precise voltage regulation.  
- **Soft-Start Function:** Prevents excessive current at startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Totem-Pole Outputs:** Capable of driving power MOSFETs or bipolar transistors.  

This information is based solely on the manufacturer's datasheet and technical documentation.
