Description and Introduction

3.5V to 42V Input, 0.5A Step-Down Converter with Eco-Mode 10-MSOP-PowerPAD -40 to 150 The TPS54040DGQR 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 42V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Output Current:** Up to 0.5A (500mA)  
- **Switching Frequency:** 100 kHz to 2.5 MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 10-pin VSSOP (DGQ)  
- **Control Method:** Voltage mode PWM  

### **Descriptions:**
- The TPS54040DGQR 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 industrial, automotive, and consumer applications.  
- The device includes features like adjustable soft-start, cycle-by-cycle current limiting, and thermal shutdown protection.  

### **Features:**
- **Wide Input Voltage Range:** Supports operation from 4.5V to 42V.  
- **Integrated MOSFETs:** Reduces external component count.  
- **Adjustable Frequency:** Allows optimization for efficiency and size.  
- **Synchronous Rectification:** Improves efficiency compared to diode-based designs.  
- **Protection Features:** Includes undervoltage lockout (UVLO), overcurrent protection (OCP), and thermal shutdown.  
- **Low Quiescent Current:** 100 µA (typical) in shutdown mode.  

This information is based solely on the manufacturer's datasheet and technical documentation.
