Description and Introduction

0.5A Constant Current Buck Regulator for High Power LED Drivers 8-VSSOP -40 to 125 The LM3402MM/NOPB is a step-down DC-DC converter manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Input Voltage Range:** 6V to 42V  
- **Output Voltage Range:** Adjustable down to 1.225V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** Adjustable (300kHz to 1MHz)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin VSSOP (MSOP)  

### **Descriptions:**  
The LM3402MM/NOPB is a constant on-time (COT) buck regulator designed for high-efficiency step-down voltage conversion. It features an integrated N-channel MOSFET and is optimized for low-power applications.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 6V to 42V input  
- **Adjustable Output Voltage:** Using an external resistor divider  
- **Adjustable Switching Frequency:** From 300kHz to 1MHz  
- **Integrated MOSFET:** Simplifies design and reduces external components  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Undervoltage Lockout (UVLO):** Ensures proper operation  
- **Cycle-by-Cycle Current Limiting:** Enhances reliability  

This device is commonly used in industrial, automotive, and general-purpose power supply applications.
