Description and Introduction

3.5V to 42V Input, 0.5A Step-Down Converter with Eco-Mode 10-MSOP-PowerPAD -40 to 150 The TPS54040DGQ is a step-down (buck) switching regulator manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 42V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Output Current:** Up to 0.5A (continuous)  
- **Switching Frequency:** 100 kHz to 2.5 MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-pin MSOP PowerPAD (DGQ)  

### **Descriptions:**  
The TPS54040DGQ is a high-efficiency, wide-input-voltage synchronous buck converter with integrated high-side and low-side MOSFETs. It is designed for applications requiring a compact power solution with high performance and flexibility.  

### **Features:**  
- **Integrated MOSFETs:** Reduces external component count.  
- **Adjustable Frequency:** Allows optimization for efficiency or size.  
- **Eco-mode™:** Enhances light-load efficiency.  
- **Soft-Start:** Limits inrush current during startup.  
- **UVLO (Undervoltage Lockout):** Ensures proper operation under low input voltage.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Synchronous Rectification:** Improves efficiency compared to diode-based designs.
