Description and Introduction

3A, Adjustable Output Voltage, Step-Down Switching Regulator The LM2576D2TR4-3.3 is a step-down (buck) switching regulator manufactured by ON Semiconductor.  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 3A  
- **Input Voltage Range:** 4.5V to 40V  
- **Switching Frequency:** 52 kHz (typical)  
- **Efficiency:** Up to 88%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  
- **Regulation Type:** PWM (Pulse Width Modulation)  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions:**  
The LM2576D2TR4-3.3 is a monolithic integrated circuit designed for step-down voltage regulation. It simplifies power supply design by requiring minimal external components. The device is suitable for various applications, including power supplies, battery chargers, and DC-DC converters.  

### **Features:**  
- **Simple and Easy to Use:** Requires only 4 external components.  
- **Fixed Output Voltage:** 3.3V (±4% tolerance).  
- **Low Power Standby Mode:** Consumes minimal current in shutdown mode.  
- **Internal Frequency Compensation:** Reduces external component count.  
- **Thermal Shutdown and Current Limit Protection:** Enhances reliability.  
- **Wide Input Voltage Range:** Supports 4.5V to 40V input.  
- **High Efficiency:** Optimized for power-saving applications.
