Description and Introduction

0.6/1.6 MHz Boost Converters With 22V Internal FET Switch in SOT-23 5-SOT-23 -40 to 125 The LM2731XMF/NOPB is a switching regulator manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 14V  
- **Output Voltage Range:** Adjustable from 1.21V to 14V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 1.6MHz or 3MHz versions available  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
The LM2731XMF/NOPB is a step-up (boost) DC-DC converter with a high switching frequency, allowing for small external components. It is designed for applications requiring efficient power conversion in a compact footprint.  

### **Features:**  
- Internal N-channel MOSFET switch  
- Adjustable output voltage  
- Low shutdown current (<1μA)  
- Thermal shutdown and current limit protection  
- Soft-start functionality  
- Small external component count  

This regulator is commonly used in battery-powered devices, LED drivers, and portable electronics.

Application Scenarios & Design Considerations

0.6/1.6 MHz Boost Converters With 22V Internal FET Switch in SOT-23 5-SOT-23 -40 to 125

Alternative Part Number

  • TPS61041DBVR --: Pin-compatible boost converter with similar input/output voltage range and switching frequency; TI is the successor to National Semiconductor, so it is a direct and reliable replacement.
  • AP3012KTR-G1 --: Boost converter with comparable 1.5A switch current and wide input range, available in SOT-23-5 package; good cost-effective alternative with similar performance.
  • MIC2288YD5-TR --: Compact boost converter offering similar switching frequency and current capability in a small package; suitable for space-constrained designs needing a drop-in style replacement.
