Description and Introduction

Dual Channel Controller with Wide Input Voltage Range The TL1453CD is a dual pulse-width modulation (PWM) controller manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage (VCC):** 3.5V to 16V  
- **Output Voltage:** Adjustable  
- **Output Current (per channel):** 200mA (sink/source)  
- **Switching Frequency:** Up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Descriptions:**
- The TL1453CD is a dual PWM controller designed for DC-DC converter applications.  
- It includes two independent PWM control circuits, error amplifiers, and adjustable oscillators.  
- Suitable for push-pull, flyback, and forward converter topologies.  
- Features include undervoltage lockout (UVLO), soft-start, and dead-time control.  

### **Features:**
- **Dual PWM Control:** Two independent channels for flexible power supply design.  
- **Wide Input Voltage Range:** Operates from 3.5V to 16V.  
- **Adjustable Frequency:** Oscillator frequency can be set using external components.  
- **Error Amplifiers:** Includes two high-gain error amplifiers for feedback control.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Dead-Time Control:** Adjustable dead time to prevent shoot-through in power switches.  
- **Thermal Shutdown:** Protects the device from overheating.  

This information is based on the manufacturer's datasheet for the TL1453CD.
