Description and Introduction

350 mA, Constant Current Output Floating Buck Switching Converter for High Power LEDs The LM3407MY is a switching regulator manufactured by National Semiconductor (NS). Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
National Semiconductor (NS)  

### **Specifications:**  
- **Type:** Step-Down (Buck) Switching Regulator  
- **Input Voltage Range:** 6V to 42V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Output Current:** Up to 1A  
- **Switching Frequency:** Adjustable (typically 50 kHz to 1 MHz)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The LM3407MY is a monolithic buck regulator designed for high-efficiency step-down voltage conversion. It integrates a high-side N-channel MOSFET and provides a compact, efficient solution for applications requiring a regulated output from a higher input voltage.  

### **Features:**  
- Wide input voltage range (6V to 42V)  
- Adjustable output voltage  
- High switching frequency capability  
- Integrated N-channel MOSFET  
- Thermal shutdown protection  
- Under-voltage lockout (UVLO)  
- Adjustable soft-start  
- Current mode control for improved transient response  

This information is based on the manufacturer's datasheet and technical documentation.
