Description and Introduction

Dual Channel Controller with Wide Input Voltage Range 16-TSSOP The TL1453CPWRG4 is a dual pulse-width modulation (PWM) controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Category:** Integrated Circuits (ICs)  
- **Type:** DC-DC Controller  
- **Topology:** Buck, Boost, Flyback, Forward  
- **Output Type:** Transistor Driver  
- **Number of Outputs:** 2  
- **Switching Frequency:** Up to 500 kHz  
- **Input Voltage (V):** 3.6V to 40V  
- **Duty Cycle (Max):** 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** TSSOP-16  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The TL1453CPWRG4 is a high-performance dual PWM controller designed for DC-DC converter applications.  
- It features two independent control loops, making it suitable for push-pull, half-bridge, or full-bridge topologies.  
- Includes an onboard 5.1V reference voltage and adjustable dead-time control.  

### **Features:**  
- **Dual PWM Control:** Two independent error amplifiers and PWM comparators.  
- **Wide Input Voltage Range:** 3.6V to 40V operation.  
- **Adjustable Dead-Time Control:** Allows optimization of power efficiency.  
- **Onboard Reference Voltage:** 5.1V ±1% accuracy.  
- **Synchronization Capability:** Can sync with an external clock.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Short-Circuit Protection:** Improves system reliability.  

This information is based on TI's official datasheet for the TL1453CPWRG4.
