Description and Introduction

3.5 to 28V Input, 2A, 570kHz Step-Down Converter with Eco-mode? 8-SOIC -40 to 150 The TPS54231DR is a step-down (buck) switching regulator manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 3.5V to 28V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Output Current:** Up to 2A continuous  
- **Switching Frequency:** 570 kHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8 (DR)  

### **Descriptions:**  
The TPS54231DR 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, including industrial, automotive, and consumer electronics.  

### **Features:**  
- **Integrated MOSFETs:** Reduces external component count.  
- **Adjustable Output Voltage:** Via external resistor divider.  
- **Wide Input Voltage Range:** Supports operation from 3.5V to 28V.  
- **Fixed Frequency PWM Control:** Ensures stable operation.  
- **Undervoltage Lockout (UVLO):** Prevents operation at low input voltages.  
- **Thermal Shutdown Protection:** Safeguards against overheating.  
- **Soft-Start:** Reduces inrush current during startup.  

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