Description and Introduction

Dual Pulse-Width-Modulation Control Circuit 16-SO The TL1451INSR is a pulse-width modulation (PWM) controller manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage (VCC):** 3.6V to 40V  
- **Output Voltage (VOUT):** Up to 40V  
- **Switching Frequency:** Adjustable up to 500kHz  
- **Output Current (per channel):** 100mA (sink/source)  
- **Duty Cycle Range:** 0% to 100%  
- **Number of Channels:** 2 (Dual)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC-16  

### **Descriptions:**
- The TL1451INSR is a dual PWM control circuit designed for DC-DC converter applications.  
- It includes an on-chip 2.5V reference voltage, error amplifiers, adjustable oscillator, dead-time control, and PWM comparators.  
- Suitable for push-pull, half-bridge, or full-bridge converter topologies.  

### **Features:**
- **Dual PWM Control:** Independent control for two channels.  
- **Wide Input Voltage Range:** Operates from 3.6V to 40V.  
- **Adjustable Dead Time:** Prevents shoot-through in power switches.  
- **On-Chip Error Amplifiers:** Enhances feedback control.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Short-Circuit Protection:** Improves system reliability.  
- **Low Standby Current:** Reduces power consumption.  

This information is based solely on the manufacturer's datasheet. For detailed application notes or design considerations, refer to Texas Instruments' official documentation.

Application Scenarios & Design Considerations

Dual Pulse-Width-Modulation Control Circuit 16-SO

Alternative Part Number

  • SG3525AN --: Industry-standard PWM controller with dual outputs and wide input range; commonly used as a functional substitute for TL1451 in switching power supply designs.
  • UC3846N --: Current-mode PWM controller offering similar dual-channel control capability and broad availability; suitable for power supply applications requiring TL1451-like regulation.
  • MC34025P --: Dual-output PWM controller with comparable oscillator and output driver features; a viable cross-manufacturer alternative for TL1451-based circuits.
