Description and Introduction

4.5V to 18V Input, 2A Synchronous Step-Down Converter with Eco-Mode? 16-QFN -40 to 85 The TPS54226RGTR is a step-down (buck) DC-DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.8V to 25V (adjustable)  
- **Output Current:** Up to 2.5A (continuous)  
- **Switching Frequency:** 570 kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 16-pin VQFN (RGTR)  

### **Descriptions:**  
- The TPS54226RGTR is a synchronous buck converter with integrated high-side and low-side MOSFETs.  
- It features a wide input voltage range, making it suitable for industrial, automotive, and consumer applications.  
- The device includes cycle-by-cycle current limiting, thermal shutdown, and undervoltage lockout for protection.  

### **Features:**  
- **Integrated MOSFETs:** Reduces external component count.  
- **Adjustable Output:** Uses an external resistor divider.  
- **High Efficiency:** Uses a synchronous rectification design.  
- **Protection Features:** Overcurrent, overtemperature, and undervoltage lockout.  
- **Soft Start:** Prevents inrush current during startup.
