Description and Introduction

SIMPLE SWITCHER? 4V to 60V, 3A Low Component Count Step-Down Regulator 5-TO-220 -40 to 125 The LM2576HVT-ADJ/NOPB is a step-down (buck) switching regulator manufactured by National Semiconductor (NSC). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.75V to 60V  
- **Adjustable Output Voltage:** 1.23V to 57V (set via external resistors)  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 52 kHz (fixed)  
- **Efficiency:** Up to 88% (depending on conditions)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  
- **Regulator Type:** Buck (Step-Down)  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions:**  
The LM2576HVT-ADJ/NOPB is a monolithic switching regulator designed for step-down voltage conversion. It simplifies power supply design by integrating a fixed-frequency oscillator, high-efficiency switch, and control circuitry. The adjustable version allows the output voltage to be set using external resistors.  

### **Features:**  
- **Simple Design:** Requires minimal external components.  
- **High Efficiency:** Reduces heat dissipation compared to linear regulators.  
- **Wide Input Voltage Range:** Suitable for automotive, industrial, and battery-powered applications.  
- **Thermal Shutdown & Current Limit:** Protects against overloads.  
- **Low Power Standby Mode:** Enhances efficiency in light-load conditions.  
- **TO-263 Package:** Provides good thermal performance.  

This regulator is commonly used in power supplies, battery chargers, and industrial systems requiring high-voltage step-down conversion.
