Description and Introduction

4.5V to 28V Input, Dual 3A Outputs, 600kHz Step-Down Converter with Internal Compensation The TPS54386 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:** 0.76V to 22V (adjustable via feedback resistor)  
- **Output Current:** Up to 3A continuous  
- **Switching Frequency:** 100 kHz to 2.5 MHz (adjustable or sync-capable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-pin VSON (3mm × 3mm)  

### **Descriptions:**
- The TPS54386 is a high-efficiency, step-down DC-DC converter with integrated MOSFETs.  
- It supports a wide input voltage range, making it suitable for industrial, automotive, and telecom applications.  
- Features adjustable soft-start and power-good monitoring for controlled startup.  

### **Features:**
- **Integrated MOSFETs:** Reduces external component count.  
- **Adjustable Frequency:** Allows optimization for efficiency or size.  
- **Synchronization Capability:** Can sync to an external clock.  
- **Protection Features:** Includes overcurrent, overtemperature, and undervoltage lockout (UVLO).  
- **Low Quiescent Current:** Improves efficiency at light loads.  
- **Adjustable Soft-Start:** Prevents inrush current issues.
