Description and Introduction

Low Input Voltage 1.5A Step Down Converter with Adjustable Output Voltage The TPS54110PWPR is a synchronous buck converter manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 17V  
- **Output Voltage Range:** 0.8V to 6V (adjustable via external resistors)  
- **Output Current:** Up to 1.5A (continuous)  
- **Switching Frequency:** 500 kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** HTSSOP-20 (PowerPAD™)  
- **Control Method:** Voltage Mode PWM  

### **Descriptions:**  
- The TPS54110PWPR 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 applications such as industrial, automotive, and consumer electronics.  
- The device includes features like soft-start, overcurrent protection, and thermal shutdown.  

### **Features:**  
- **Integrated MOSFETs:** Reduces external component count.  
- **Adjustable Output Voltage:** Set via external feedback resistors.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within input voltage range.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Soft-Start:** Reduces inrush current during startup.  
- **PowerPAD™ Package:** Enhances thermal performance.
