Description and Introduction

SIMPLE SWITCHER? 4V to 40V, 5A Step-Up Wide Vin Flyback Regulator 5-TO-220 -40 to 125 The LM2587T-ADJ/NOPB is a switching regulator manufactured by Texas Instruments (NS). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4V to 40V  
- **Adjustable Output Voltage:** 1.23V to 60V  
- **Output Current:** Up to 5A (depending on configuration)  
- **Switching Frequency:** 100 kHz (fixed)  
- **Efficiency:** Up to 88%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-220-5 (Through-Hole)  
- **Regulation Type:** Buck, Boost, Flyback, or Forward  

### **Descriptions:**  
The LM2587T-ADJ/NOPB is a monolithic integrated circuit designed for step-up (boost), step-down (buck), flyback, and forward converter applications. It includes a 5A switch, an oscillator, and voltage feedback control circuitry. The adjustable version allows users to set the output voltage using external resistors.  

### **Features:**  
- **Wide Input Voltage Range:** 4V to 40V  
- **High Output Current Capability:** Up to 5A  
- **Adjustable Output Voltage** (via external resistors)  
- **Internal Current Limiting & Thermal Shutdown**  
- **Low Standby Current:** 50µA (typical)  
- **Fixed Frequency Operation:** 100 kHz  
- **Suitable for Multiple Topologies:** Buck, Boost, Flyback, Forward  

This information is based on the manufacturer's datasheet.
