- **Package Type:** TO-263 (D2PAK)  

### **Descriptions:**
The LM2590HVS-ADJ is a monolithic integrated circuit that provides all active functions for a step-down (buck) switching regulator. It is designed to drive a 3A load with excellent line and load regulation. The adjustable version allows the output voltage to be set with an external resistor divider.  

### **Features:**
- **Wide Input Voltage Range:** 4.5V to 40V  
- **3A Output Current Capability**  
- **Adjustable Output Voltage**  
- **Internally Fixed Frequency Oscillator (150 kHz)**  
- **Thermal Shutdown and Current Limit Protection**  
- **Low Power Standby Mode (IQ < 80 µA)**  
- **Uses Readily Available Standard Inductors**  
- **Simple and Easy to Design**  

This regulator is suitable for applications such as power supplies, industrial controls, automotive systems, and battery chargers.
