Description and Introduction

3.0 A, 15 V, Step−Down Switching Regulator The LM2576D2TR4-5G is a step-down (buck) switching voltage regulator manufactured by ON Semiconductor.  

### **Specifications:**  
- **Output Voltage:** 5V (fixed)  
- **Output Current:** Up to 3A  
- **Input Voltage Range:** 4.5V to 40V  
- **Switching Frequency:** 52 kHz (typical)  
- **Efficiency:** Up to 88% (depending on conditions)  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package Type:** TO-263-5 (D2PAK)  
- **Regulation Type:** PWM (Pulse Width Modulation)  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions:**  
The LM2576D2TR4-5G is a monolithic integrated circuit optimized for step-down voltage regulation. It simplifies power supply design by requiring minimal external components and provides high efficiency for applications requiring a stable 5V output.  

### **Features:**  
- Simple and easy-to-use buck regulator  
- Requires only 4 external components  
- Internal frequency compensation  
- Low standby current (50 µA typical in shutdown mode)  
- Wide input voltage range  
- Available in fixed and adjustable output versions  
- Overcurrent and thermal protection  

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