Description and Introduction

9-42V Wide Vin, 0.5A, Constant On-Time Non-Synchronous Buck Regulator 8-WSON -40 to 125 The LM25007SDX/NOPB is a switching regulator IC manufactured by National Semiconductor (NSC). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 6V to 42V  
- **Output Voltage Range:** Adjustable from 1.225V to 37V  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** Adjustable from 50kHz to 1MHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Pin LLP (Leadless Leadframe Package)  

### **Descriptions:**
- The LM25007SDX/NOPB is a step-down (buck) switching regulator designed for high-efficiency power conversion.  
- It integrates a high-side N-channel MOSFET and control circuitry for simplified design.  
- Suitable for automotive, industrial, and telecom applications requiring wide input voltage ranges.  

### **Features:**
- **Wide Input Voltage Range:** Supports 6V to 42V operation.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Integrated MOSFET:** Reduces external component count.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency or size.  
- **Cycle-by-Cycle Current Limiting:** Protects against overloads.  
- **Thermal Shutdown:** Prevents damage from excessive heat.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Low Quiescent Current:** Improves efficiency at light loads.  

This information is based solely on the manufacturer's datasheet.
