Description and Introduction

SIMPLE SWITCHER 3-Amp Flyback Regulator 7-DDPAK/TO-263 -40 to 125 The LM2586S-ADJ/NOPB is a switching regulator IC manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Input Voltage Range:** 4V to 40V  
- **Output Voltage Range:** Adjustable from 1.23V to 37V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 100 kHz (fixed)  
- **Efficiency:** Up to 88%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  
- **Regulator Type:** Buck (Step-Down)  
- **Feedback Voltage:** 1.23V (reference)  
- **Duty Cycle:** Up to 98%  

### **Descriptions:**
The LM2586S-ADJ/NOPB is a monolithic step-down switching regulator designed for easy implementation in high-efficiency power supply applications. It integrates a 3A switch, frequency compensation, and a fixed oscillator, reducing external component count. The adjustable output version allows for flexible voltage settings using external resistors.

### **Features:**
- **Wide Input Voltage Range (4V to 40V)**  
- **3A Output Current Capability**  
- **Internal Current Limiting & Thermal Shutdown**  
- **Adjustable Output Voltage (1.23V to 37V)**  
- **Low Standby Current (50µA typical)**  
- **Requires Minimal External Components**  
- **High Efficiency (Up to 88%)**  
- **TO-263 Package for Improved Thermal Performance**  

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