Partnumber Manufacturer Quantity Availability
TL1451CNS 590 In Stock

Description and Introduction

Dual Pulse-Width-Modulation Control Circuit 16-SO The TL1451CNS is a pulse-width modulation (PWM) controller IC manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage (VCC):** 3.6V to 40V  
- **Output Voltage:** Adjustable via external components  
- **Oscillator Frequency Range:** 1kHz to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Output Current (Sink/Source):** 200mA per channel  
- **Number of Channels:** 2 (Dual PWM Controller)  
- **Operating Temperature Range:** -20°C to +85°C  
- **Package:** SOIC-16  

### **Descriptions:**  
- The TL1451CNS is a dual PWM control circuit designed for DC-DC converter applications.  
- It includes an on-chip oscillator, error amplifiers, and adjustable dead-time control.  
- Suitable for push-pull and buck/boost converter topologies.  

### **Features:**  
- **Dual PWM Control:** Independent control for two channels.  
- **Adjustable Dead Time:** Prevents shoot-through in power switches.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low voltage conditions.  
- **Error Amplifiers:** High-gain comparators for feedback regulation.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Wide Supply Voltage Range:** Supports 3.6V to 40V input.  

This information is based solely on the manufacturer's datasheet.
