Description and Introduction

Thin SOT23 1A Load Step-Down DC-DC Regulator 6-SOT -40 to 125 The LM2734XMK/NOPB is a switching regulator manufactured by Texas Instruments (NS). Below are the factual details from Ic-phoenix technical data files:  

### **Manufacturer:**  
- **NS (National Semiconductor, now part of Texas Instruments)**  

### **Pb-free Specifications:**  
- **RoHS Compliant:** Yes  
- **Lead-Free:** Yes  
- **Halogen-Free:** No specific data provided  

### **Descriptions:**  
- The LM2734XMK/NOPB is a **step-up (boost) DC-DC switching regulator**.  
- It operates at a **fixed switching frequency of 1.6 MHz or 3.3 MHz** (depending on the variant).  
- Input voltage range: **2.7V to 14V**  
- Output voltage: **Adjustable up to 24V**  
- Output current capability: **Up to 2.1A (switch current limit)**  
- Package: **6-Pin SOT-23 (XMK)**  

### **Features:**  
- **High switching frequency** allows for small external components.  
- **Internal N-channel MOSFET switch** for high efficiency.  
- **Low shutdown current (<1 µA)** for power-saving applications.  
- **Thermal shutdown and current limit protection** for reliability.  
- **Adjustable soft-start** to control inrush current.  
- **Synchronous rectification not included** (external diode required).  

This information is strictly based on the available specifications for the LM2734XMK/NOPB.
