Description and Introduction

SIMPLE SWITCHER? 4.5V to 40V, 3A Low Component Count Step-Down Regulator 5-TO-220 The LM2596T-5.0/NOPB is a step-down (buck) switching regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** Fixed 5.0V  
- **Output Current:** Up to 3A  
- **Input Voltage Range:** 4.5V to 40V  
- **Switching Frequency:** 150 kHz  
- **Efficiency:** Up to 88%  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package Type:** TO-220-5 (Through-Hole)  
- **Regulation Type:** Switching Regulator  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions:**  
The LM2596T-5.0/NOPB is a monolithic integrated circuit that provides all active functions for a step-down switching regulator. It is designed for easy implementation and requires minimal external components. The fixed 5.0V output version simplifies design by eliminating the need for external feedback resistors.  

### **Features:**  
- **Simple and Easy to Use** – Requires only 4 external components.  
- **Internal Frequency Compensation** – Reduces external component count.  
- **Fixed Output Voltage** – Eliminates the need for feedback resistors.  
- **High Efficiency** – Up to 88% efficiency.  
- **Wide Input Voltage Range** – Supports 4.5V to 40V input.  
- **Thermal Shutdown & Current Limit Protection** – Enhances reliability.  
- **TO-220 Package** – Suitable for through-hole mounting.  

This regulator is commonly used in power supply applications, battery chargers, and industrial systems.
