Description and Introduction

Thin SOT23 1A Load Step-Down DC-DC Regulator 6-WSON -40 to 125 The LM2734ZSD/NOPB is a switching regulator manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Input Voltage Range:** 3V to 20V  
- **Output Voltage Range:** Adjustable from 1.21V to 20V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 1.6MHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-6 (Thin Shrink Small Outline Package)  
- **Topology:** Step-Up (Boost) DC-DC Converter  
- **Duty Cycle:** Up to 90%  
- **Quiescent Current:** 1.5mA (typical)  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The LM2734ZSD/NOPB is a high-efficiency, fixed-frequency step-up DC-DC converter designed for battery-powered and portable applications. It integrates a power MOSFET switch and provides a compact solution for generating higher output voltages from low input sources.  

### **Features:**  
- **Fixed 1.6MHz Switching Frequency** (Reduces external component size)  
- **Internal N-Channel MOSFET Switch** (Eliminates need for external FET)  
- **Low Shutdown Current** (<1µA) for power-saving modes  
- **Cycle-by-Cycle Current Limiting** for overcurrent protection  
- **Thermal Shutdown Protection**  
- **Adjustable Output Voltage via External Resistors**  
- **Small SOT-23-6 Package** (Saves board space)  
- **Wide Input Voltage Range** (3V to 20V)  

This information is strictly based on the manufacturer's datasheet and technical documentation.
