Description and Introduction

Dual Channel Controller with Wide Input Voltage Range The TL1453CN is a dual pulse-width modulation (PWM) controller manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TL1453CN  
- **Type:** Dual PWM Controller  
- **Package:** PDIP-16 (Plastic Dual In-Line Package)  
- **Operating Voltage Range:** 3.6V to 50V  
- **Output Current:** 200mA (sink/source per channel)  
- **Switching Frequency:** Adjustable up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 1MHz (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The TL1453CN is a high-performance dual PWM controller designed for power supply and DC-DC converter applications. It features two independent PWM control circuits, each with its own error amplifier, oscillator, and output stage. The device supports adjustable frequency operation and provides precise voltage regulation.  

### **Features:**  
- **Dual PWM Control:** Two independent PWM channels for flexible power supply designs.  
- **Wide Input Voltage Range:** Operates from 3.6V to 50V, suitable for various applications.  
- **Adjustable Frequency:** External resistor/capacitor allows frequency adjustment up to 500kHz.  
- **Error Amplifiers:** High-gain bandwidth (1MHz) for accurate feedback control.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Totem-Pole Outputs:** Capable of sourcing/sinking 200mA for driving power MOSFETs.  
- **Thermal Protection:** Internal thermal shutdown prevents overheating.  

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