Description and Introduction

7.5A Adj LDO Linear Regulator in a TO-263 5-Leads package The part **IRU1175CM** is a **synchronous buck converter** manufactured by **IOR (Integrated Operational Resources)**. Below are the key specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 18V  
- **Output Voltage:** Adjustable (0.8V to 5.5V)  
- **Output Current:** Up to 15A  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin QFN (5mm x 5mm)  

### **Descriptions:**  
- The **IRU1175CM** is a high-efficiency, synchronous step-down DC-DC converter designed for point-of-load (POL) applications.  
- It integrates **MOSFET drivers** and **power MOSFETs**, reducing external component count.  
- Supports **adjustable soft-start** and **voltage tracking** for sequencing requirements.  

### **Features:**  
- **Integrated Power MOSFETs** (high-side and low-side)  
- **Adjustable Output Voltage** via external resistors  
- **Programmable Switching Frequency** (300kHz to 1MHz)  
- **Overcurrent, Overtemperature, and Undervoltage Protection**  
- **Precision Reference Voltage (±1%)**  
- **External Synchronization Capability**  
- **Low Quiescent Current** in standby mode  

This information is based on IOR's technical documentation for the **IRU1175CM**. For exact application details, refer to the official datasheet.

Application Scenarios & Design Considerations
