Description and Introduction

5.5V to 36V Input, 2A, 500kHz Step-Down Converter 8-SOIC -40 to 125 The TPS5420DR is a step-down (buck) DC-DC converter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 5.5V to 36V  
- **Output Voltage Range:** Adjustable down to 1.22V (reference voltage)  
- **Output Current:** Up to 2A continuous  
- **Switching Frequency:** 500 kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** SOIC-8 (DR)  

### **Descriptions:**  
The TPS5420DR is a synchronous buck converter with integrated high-side and low-side MOSFETs. It provides a compact, efficient solution for step-down voltage regulation in various applications.  

### **Features:**  
- **Integrated MOSFETs:** Reduces external component count  
- **Adjustable Output Voltage:** Set via external resistors  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage  
- **Thermal Shutdown:** Protects the device from overheating  
- **Soft-Start:** Reduces inrush current during startup  
- **Current Mode Control:** Improves transient response and stability  

This information is based solely on the manufacturer's datasheet.
