Description and Introduction

0.6/1.6 MHz Boost Converters With 22V Internal FET Switch in SOT-23 The LM2731YMFX is a switching regulator manufactured by National Semiconductor (NS国半). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 2.7V to 14V  
- **Output Voltage Range:** Adjustable from 1.23V to 14V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 1.6MHz (LM2731X) or 3MHz (LM2731Y)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**
- The LM2731YMFX is a step-up (boost) DC-DC converter designed for small, low-power applications.  
- It integrates a high-side N-channel MOSFET switch for efficient power conversion.  
- The device operates at a fixed switching frequency (3MHz for the "Y" version), allowing for small external components.  
- It includes features like thermal shutdown, current limiting, and undervoltage lockout (UVLO) for protection.  

### **Features:**
- **High Switching Frequency:** Enables the use of small inductors and capacitors.  
- **Low Quiescent Current:** Typically 1.1mA.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Mode Control:** Provides stable operation and fast transient response.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  

This information is strictly based on the manufacturer's datasheet for the LM2731YMFX.
