- **Package:** TO-263 (D2PAK)  

### **Descriptions:**  
The LM2574HVMX-15 is a step-down (buck) switching regulator designed for high-efficiency voltage conversion. It integrates a 52 kHz oscillator, a high-voltage switch, and control circuitry, reducing the need for external components.  

### **Features:**  
- **Fixed 15V Output**  
- **Wide Input Voltage Range (4.5V to 60V)**  
- **Low Power Standby Mode (50µA typical)**  
- **Thermal Shutdown & Current Limiting Protection**  
- **Requires Only 4 External Components**  
- **Available in TO-263 Package**  

This regulator is commonly used in power supply applications requiring high efficiency and compact design.
