Description and Introduction

SIMPLE SWITCHER 3-Amp Flyback Regulator The LM2585S-5.0 is a switching regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 5.0V (fixed)  
- **Input Voltage Range:** 4V to 40V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 100 kHz (typical)  
- **Efficiency:** Up to 80%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (SMD)  

### **Descriptions:**
The LM2585S-5.0 is a monolithic integrated circuit designed for step-down (buck) switching regulator applications. It simplifies power supply design by integrating a high-efficiency switching regulator with a fixed 5.0V output. The device is suitable for a wide range of industrial, automotive, and consumer applications requiring a stable 5V supply from higher input voltages.

### **Features:**
- **Fixed 5.0V Output**  
- **3A Output Current Capability**  
- **Wide Input Voltage Range (4V to 40V)**  
- **Internal Current Limiting and Thermal Shutdown**  
- **Low Standby Current (50µA typical in shutdown mode)**  
- **Requires Few External Components**  
- **High Efficiency (Up to 80%)**  
- **TO-263 Surface-Mount Package**  

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