Description and Introduction

SIMPLE SWITCHER 1A Step-Down Voltage Regulator The LM2575HVS-12 is a step-down (buck) switching voltage regulator manufactured by ON Semiconductor (NS). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Output Voltage:** Fixed 12V  
- **Input Voltage Range:** 4.75V to 40V (HV version)  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 52 kHz (typical)  
- **Efficiency:** Up to 88% (depending on conditions)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-220-5 (through-hole)  
- **Regulation Type:** PWM (Pulse Width Modulation)  
- **Protection Features:** Thermal shutdown, current limiting  

### **Description:**  
The LM2575HVS-12 is a monolithic integrated circuit designed for step-down voltage regulation applications. It simplifies power supply design by requiring minimal external components and provides high efficiency for DC-DC conversion. The fixed 12V output version eliminates the need for external feedback resistors.

### **Features:**  
- **Simple and Easy to Use:** Requires only 4 external components.  
- **High Efficiency:** Reduces power dissipation.  
- **Wide Input Voltage Range (4.75V–40V):** Suitable for automotive and industrial applications.  
- **Fixed 12V Output:** No feedback resistors needed.  
- **Thermal Shutdown and Current Limiting:** Protects against overloads.  
- **Low Power Standby Mode:** Consumes minimal current in shutdown mode.  
- **TO-220 Package:** Robust and suitable for through-hole mounting.
