Description and Introduction

Dual Output Synchronous Buck Controller with Wide Input Voltage Range The TPS5102IDBT is a dual-output power controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage 1 (Buck Regulator):** Adjustable from 1.22V to 5.5V  
- **Output Voltage 2 (Linear Regulator):** Fixed 3.3V or 5V (selectable)  
- **Switching Frequency:** 300kHz (typical)  
- **Buck Converter Output Current:** Up to 2A  
- **Linear Regulator Output Current:** Up to 500mA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin SSOP (DBT)  

### **Descriptions:**  
The TPS5102IDBT integrates a synchronous buck regulator and a linear regulator, providing a compact dual-output power solution. It is designed for applications requiring efficient power conversion with stable voltage outputs.  

### **Features:**  
- **Dual Outputs:** Combines a step-down converter and an LDO in one IC.  
- **Adjustable Buck Output:** Feedback pin allows output voltage adjustment.  
- **Fixed Linear Regulator Output:** Selectable 3.3V or 5V.  
- **Synchronous Rectification:** Improves efficiency.  
- **Soft-Start:** Reduces inrush current.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage.  
- **Thermal Shutdown:** Protects against overheating.  

This device is commonly used in networking, industrial, and consumer electronics applications.
