Description and Introduction

Hysteretic PFET Controller for High Power LED Drive The LM3401MM is a switching regulator manufactured by National Semiconductor (NS).  

**Specifications:**  
- **Input Voltage Range:** 6V to 42V  
- **Output Voltage Range:** Adjustable down to 1.25V  
- **Switching Frequency:** Adjustable up to 1MHz  
- **Maximum Output Current:** 1.5A (dependent on external components)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin MSOP  

**Descriptions:**  
The LM3401MM is a step-down (buck) switching regulator designed for high-efficiency DC-DC conversion. It integrates a high-side N-channel MOSFET driver and provides constant-current or constant-voltage output regulation.  

**Features:**  
- Wide input voltage range (6V to 42V)  
- Adjustable switching frequency (up to 1MHz)  
- Precision 1.25V reference voltage  
- Cycle-by-cycle current limiting  
- Thermal shutdown protection  
- Under-voltage lockout (UVLO)  
- Adjustable soft-start  
- Small MSOP-8 package for space-constrained applications
