Description and Introduction

Synchronous Buck Controller with Wide Input Voltage Range The TPS5103IDB is a synchronous buck controller manufactured by Texas Instruments. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 0.9V to 5.5V  
- **Switching Frequency:** 300kHz (fixed)  
- **Output Current:** Up to 10A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin SSOP (DB)  

### **Descriptions:**  
- The TPS5103IDB is a high-efficiency synchronous buck controller designed for step-down DC-DC conversion.  
- It integrates PWM control and gate drivers for external N-channel MOSFETs.  
- Supports adjustable output voltage via an external resistor divider.  
- Features include soft-start, overcurrent protection, and undervoltage lockout (UVLO).  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Adjustable Soft-Start:** Limits inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Overcurrent Protection:** Safeguards the circuit from excessive current.  
- **Fixed Frequency Operation:** 300kHz switching for predictable noise performance.  
- **Wide Input Voltage Range:** Suitable for various power supply applications.
