Description and Introduction

0.6/1.6 MHz Boost Converters With 40V Internal FET Switch in SOT-23 The LM2733YMF is a switching regulator from National Semiconductor (NS国半). Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 3V to 20V  
- **Output Voltage Range:** 1.21V to 20V (adjustable via external resistors)  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 1.6MHz or 550kHz (selectable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-6 (YMF)  

### **Descriptions:**  
- The LM2733YMF is a step-up (boost) DC-DC converter with an integrated N-channel MOSFET.  
- It is designed for high-efficiency power conversion in battery-powered and industrial applications.  
- The device includes features like thermal shutdown, current limiting, and soft-start for reliable operation.  

### **Features:**  
- **Adjustable Output Voltage** (via external feedback resistors)  
- **High Switching Frequency** (1.6MHz or 550kHz) for compact designs  
- **Integrated N-Channel MOSFET** (reduces external component count)  
- **Thermal Shutdown Protection**  
- **Current Limiting and Soft-Start**  
- **Low Shutdown Current** (<1µA)  

This information is based on the manufacturer's datasheet for the LM2733YMF.
