Description and Introduction

Hysteretic PFET Controller for High Power LED Drive 8-VSSOP -40 to 125 The LM3401MM/NOPB is a switching regulator IC manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 6V to 42V  
- **Output Voltage Range:** Adjustable from 1.285V to 37V  
- **Output Current:** Up to 1.5A (depending on external components)  
- **Switching Frequency:** Adjustable from 50kHz to 1MHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin VSSOP (MSOP)  

### **Descriptions:**  
The LM3401MM/NOPB is a step-down (buck) DC-DC switching regulator designed for high-efficiency power conversion. It integrates a high-side N-channel MOSFET driver and supports constant-on-time (COT) control for fast transient response. It is suitable for applications requiring wide input voltage ranges and adjustable output voltages.  

### **Features:**  
- **Wide Input Voltage Range (6V–42V)**  
- **Adjustable Output Voltage (1.285V–37V)**  
- **Constant-On-Time (COT) Control**  
- **Adjustable Switching Frequency (50kHz–1MHz)**  
- **Internal High-Side MOSFET Driver**  
- **Thermal Shutdown Protection**  
- **Undervoltage Lockout (UVLO)**  
- **Low Quiescent Current (2.5mA typical)**  
- **RoHS Compliant**  

This device is commonly used in industrial, automotive, and LED driver applications.
