Description and Introduction

52kHz Simple 3A Buck Voltage Regulator The LM2576-12BU is a step-down (buck) switching regulator manufactured by Microchip Technology (formerly Micrel). Below are its specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Output Voltage:** Fixed 12V
- **Output Current:** Up to 3A
- **Input Voltage Range:** 4.75V to 40V
- **Switching Frequency:** 52 kHz (typical)
- **Efficiency:** Up to 88% (depending on conditions)
- **Operating Temperature Range:** -40°C to +125°C
- **Package:** TO-263-5 (D2PAK)
- **Regulation Type:** Buck (Step-Down) Switching Regulator

### **Descriptions:**
- The LM2576-12BU 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 12V output version eliminates the need for external resistors to set the output voltage.
- It includes internal frequency compensation, a fixed-frequency oscillator, and thermal shutdown protection.

### **Features:**
- **3A Output Current Capability**
- **Wide Input Voltage Range (4.75V to 40V)**
- **Fixed 12V Output (±4% Regulation)**
- **Internal Frequency Compensation**
- **52 kHz Fixed Frequency Internal Oscillator**
- **Thermal Shutdown and Current Limit Protection**
- **Low Power Standby Mode (IQ < 50μA)**
- **Requires Only 4 External Components for Operation**
- **Available in TO-263-5 (D2PAK) Package**

Description and Introduction

52kHz Simple 3A Buck Voltage Regulator The LM2576-12BU is a step-down (buck) switching voltage regulator manufactured by ON Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** Fixed 12V  
- **Output Current:** Up to 3A  
- **Input Voltage Range:** 7V to 40V  
- **Switching Frequency:** 52 kHz  
- **Efficiency:** Up to 88%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  
- **Regulation Type:** Switching Regulator  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions and Features:**  
- **Simple and Efficient:** Requires minimal external components for operation.  
- **Fixed Output:** Pre-set to 12V, eliminating the need for external feedback resistors.  
- **Wide Input Range:** Suitable for automotive, industrial, and battery-powered applications.  
- **Low Power Standby Mode:** Reduces power consumption in shutdown mode.  
- **Robust Design:** Includes thermal protection and current limiting for reliability.  
- **High Efficiency:** Reduces heat dissipation compared to linear regulators.  

This regulator is commonly used in power supply designs for DC-DC conversion where stable 12V output is required.
