Description and Introduction

3.5V to 28V Input, 2A, 1MHz Step-Down Converter with Eco-mode 8-SOIC -40 to 150 The TPS54232DR is a step-down (buck) DC-DC converter manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Output Current:** Up to 2A continuous  
- **Switching Frequency:** 570 kHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin SOIC (DR)  

### **Descriptions:**  
The TPS54232DR is a synchronous buck converter with integrated high-side and low-side MOSFETs. It provides a compact, efficient solution for step-down voltage regulation in applications such as industrial, automotive, and consumer electronics.  

### **Features:**  
- **Integrated MOSFETs:** Reduces external component count.  
- **Adjustable Output Voltage:** Via external resistor divider.  
- **Wide Input Voltage Range:** Supports 4.5V to 28V input.  
- **Fixed Switching Frequency:** 570 kHz for predictable performance.  
- **Overcurrent Protection:** Includes hiccup mode for fault recovery.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Low Quiescent Current:** Improves efficiency at light loads.  

This information is sourced from the official Texas Instruments datasheet for the TPS54232DR.
