Description and Introduction

Low Input Voltage 3A Synchronous Buck Converter with Disabled Sinking During Start Up The TPS54373 is a synchronous buck converter manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.8V to 22V (adjustable via external resistors)  
- **Output Current:** Up to 3A (continuous)  
- **Switching Frequency:** 300 kHz to 2.2 MHz (adjustable or synchronized to an external clock)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin SOIC (DDA) and 8-pin WSON (DRC)  

### **Descriptions:**  
- The TPS54373 is a **step-down (buck) DC-DC converter** with integrated high-side and low-side MOSFETs.  
- It is designed for **high-efficiency power conversion** in industrial, automotive, and consumer applications.  
- Features **adaptive on-time control** for fast transient response and stable operation.  
- Supports **low-power mode (Eco-mode)** for improved efficiency at light loads.  

### **Features:**  
- **Integrated MOSFETs:** Reduces external component count.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency or size.  
- **Wide Input Voltage Range:** Suitable for various power sources.  
- **Power Good (PG) Output:** Monitors output voltage status.  
- **Soft-Start & Pre-Biased Startup:** Prevents inrush current and supports pre-biased outputs.  
- **Overcurrent & Thermal Protection:** Enhances system reliability.
