SIMPLE SWITCHER Power Converter 150 KHz 1A Step-Down Voltage Regulator, with Features The LM2598T-ADJ is a step-down (buck) switching voltage regulator manufactured by ON Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Voltage Range:** Adjustable from 1.23V to 37V (using external resistors)  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 150 kHz (fixed)  
- **Efficiency:** Up to 92%  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** TO-220-5 (Through-Hole)  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions:**  
The LM2598T-ADJ is a monolithic integrated circuit that provides all active functions for a step-down (buck) switching regulator. It is designed for simple and efficient voltage conversion, requiring minimal external components. The adjustable output version allows for flexibility in setting the desired output voltage.  

### **Features:**  
- **Adjustable Output Voltage** (via external resistors)  
- **3A Output Current Capability**  
- **Wide Input Voltage Range** (4.5V to 40V)  
- **Internal Frequency Compensation**  
- **Low Power Standby Mode** (IQ typically 80µA)  
- **Thermal Shutdown and Current Limit Protection**  
- **TO-220 Package for Easy Mounting**  

This regulator is commonly used in power supply designs for industrial, automotive, and consumer applications.
