Description and Introduction

550kHz/1.6MHz 1.5A Step-Down DC-DC Switching Regulator 8-WSON -40 to 125 The LM2738XSD/NOPB is a switching regulator from National Semiconductor (NSC). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 3V to 20V  
- **Output Voltage Range:** Adjustable from 1.21V to 20V  
- **Output Current:** Up to 1.6A  
- **Switching Frequency:** 1.6MHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 6-Pin WSON (3mm x 3mm)  

### **Description:**
The LM2738XSD/NOPB is a step-up (boost) DC-DC converter with an integrated 1.6A switch. It is designed for high-efficiency power conversion in space-constrained applications. The fixed-frequency PWM architecture ensures stable performance with minimal external components.

### **Features:**
- **Integrated Power MOSFET:** Reduces external component count.  
- **Fixed-Frequency Operation:** 1.6MHz for compact designs.  
- **Low Shutdown Current:** <1µA in shutdown mode.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Current Limit Protection:** Enhances reliability.  
- **Adjustable Output Voltage:** Via external resistors.  
- **Small Footprint:** WSON package suitable for portable devices.  

This part is ideal for battery-powered applications, LED drivers, and portable electronics requiring efficient power conversion.
