- **Package:** TO-263-5 (D2PAK)  
- **Regulation Type:** PWM (Pulse Width Modulation)  
- **Protection Features:**  
  - Thermal shutdown  
  - Current limit  

### **Descriptions:**  
The LM2592HVSX-3.3 is a monolithic integrated circuit that provides all active functions for a step-down switching regulator. It is designed for high-efficiency power conversion and is capable of driving a 2A load with excellent line and load regulation.  

### **Features:**  
- **Wide Input Voltage Range:** 4.5V to 40V  
- **Fixed 3.3V Output Voltage**  
- **High Efficiency (Up to 88%)**  
- **150 kHz Fixed-Frequency Internal Oscillator**  
- **Low Power Standby Mode (IQ < 80µA)**  
- **Thermal Shutdown and Current Limit Protection**  
- **Simple External Components Required**  
- **Available in TO-263-5 Package**  

This regulator is commonly used in power supply applications requiring a stable 3.3V output from a higher input voltage source.
