Description and Introduction

Dual Output Synchronous Buck Controller with Wide Input Voltage Range The TPS5102IDBTR is a dual-output power supply controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage 1 (Buck Converter):** Adjustable from 0.9V to 5.5V  
- **Output Voltage 2 (Linear Regulator):** Fixed 5V or 3.3V (selectable)  
- **Switching Frequency:** 300kHz (typical)  
- **Buck Converter Output Current:** Up to 2A  
- **Linear Regulator Output Current:** Up to 500mA  
- **Efficiency:** Up to 95% (Buck Converter)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6 (DBT)  

### **Descriptions:**  
The TPS5102IDBTR integrates a synchronous buck converter and a linear regulator in a single package. It is designed for applications requiring dual power rails, such as networking, industrial, and consumer electronics. The buck converter provides high efficiency, while the linear regulator offers a low-noise output.  

### **Features:**  
- **Dual Outputs:** Combines a buck converter and linear regulator.  
- **Adjustable Buck Output:** 0.9V to 5.5V via external resistors.  
- **Selectable Linear Regulator Output:** 5V or 3.3V (fixed).  
- **Synchronous Rectification:** Improves efficiency.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Soft-Start:** Reduces inrush current.  

This information is based on the manufacturer's datasheet. For detailed specifications, refer to the official TI documentation.

Application Scenarios & Design Considerations
