Description and Introduction

SIMPLE SWITCHER? 4V to 40V, 3A Step-Up Wide Vin Flyback Regulator 5-DDPAK/TO-263 -40 to 125 The LM2585SX-ADJ/NOPB is a switching regulator manufactured by Texas Instruments (NS). Below are its key specifications, descriptions, and features:

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

### **Descriptions:**
The LM2585SX-ADJ/NOPB is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator. It is designed for simple and efficient power supply designs, capable of driving a 3A load with excellent line and load regulation.  

### **Features:**
- Adjustable output voltage via external resistors  
- Internal current limiting and thermal shutdown protection  
- Low standby current (50µA typical)  
- Requires minimal external components  
- Wide input voltage range  
- High efficiency operation  

This regulator is commonly used in automotive, industrial, and consumer applications where a stable and efficient DC-DC conversion is required.  

(Note: "NS" refers to National Semiconductor, which was acquired by Texas Instruments.)
