Description and Introduction

SIMPLE SWITCHER Power Converter 150 kHz 0.5A Step-Down Voltage Regulator The LM2594HVM-3.3 is a step-down (buck) switching voltage regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Current:** Up to 0.5A  
- **Switching Frequency:** 150 kHz (fixed)  
- **Efficiency:** Up to 80%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK)  
- **Regulator Type:** Buck Converter  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions:**  
The LM2594HVM-3.3 is a monolithic integrated circuit designed for step-down voltage regulation. It provides a fixed 3.3V output and is capable of driving loads up to 0.5A. The device is optimized for high efficiency and low power dissipation.  

### **Features:**  
- Simple and easy-to-use design  
- Requires minimal external components  
- Internal frequency compensation  
- Low standby current in shutdown mode  
- Adjustable soft-start capability  
- Wide input voltage range  
- Thermal shutdown and current limit protection  

This regulator is commonly used in power supply applications where a stable 3.3V output is required from higher input voltages.
