Description and Introduction

1A Driver Transistor Built-In Step-Down DC/DC Converters Here are the factual details about the **TOREX XC9223B081AR** from Ic-phoenix technical data files:  

### **Manufacturer**: TOREX  
### **Part Number**: XC9223B081AR  

### **Specifications**:  
- **Type**: Step-Down DC/DC Converter (Buck Regulator)  
- **Input Voltage Range**: 2.5V to 6.0V  
- **Output Voltage**: Fixed (0.8V)  
- **Output Current**: Up to 1.5A  
- **Switching Frequency**: 1.2MHz (Typical)  
- **Efficiency**: Up to 95%  
- **Quiescent Current**: 30μA (Typical)  
- **Operation Temperature Range**: -40°C to +85°C  
- **Package**: SOT-25 (5-pin)  

### **Descriptions and Features**:  
- **High Efficiency**: Uses synchronous rectification for improved power conversion.  
- **Low Power Consumption**: Features a built-in auto-discharge function when disabled.  
- **Fixed Output Voltage**: Pre-set to 0.8V, eliminating the need for external resistors.  
- **Soft-Start Function**: Reduces inrush current during startup.  
- **Protection Features**: Includes overcurrent protection (OCP) and thermal shutdown (TSD).  
- **Compact Design**: Small SOT-25 package suitable for space-constrained applications.  
- **Applications**: Used in portable devices, IoT, and battery-powered systems.  

This information is based solely on the available specifications and features from TOREX's documentation.
