Description and Introduction

Dual Channel Controller with Wide Input Voltage Range The TL1453CNSR is a dual pulse-width modulation (PWM) controller manufactured by Texas Instruments (TEXAS). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TEXAS)  
- **Part Number:** TL1453CNSR  
- **Type:** Dual PWM Controller  
- **Package:** SOIC-16 (Surface Mount)  
- **Operating Voltage Range:** 3.6V to 40V  
- **Output Current:** 200mA (sink/source per channel)  
- **Switching Frequency:** Adjustable up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The TL1453CNSR is a dual PWM controller designed for power supply and DC-DC converter applications.  
- It features two independent PWM control circuits, making it suitable for push-pull, half-bridge, or full-bridge topologies.  
- The device includes an error amplifier, oscillator, dead-time control, and output drivers for each channel.  

### **Features:**  
- **Dual PWM Control:** Independent control for two outputs.  
- **Adjustable Frequency:** External resistor/capacitor sets switching frequency.  
- **Error Amplifiers:** Built-in for voltage feedback regulation.  
- **Dead-Time Control:** Adjustable to prevent shoot-through in bridge circuits.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Soft-Start Capability:** Reduces inrush current during startup.  

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