Description and Introduction

FORWARD SYNCHRONOUS RECTIFIERS SMART DRIVER The STSR2PMCD-TR is a synchronous step-down controller manufactured by STMicroelectronics (STM).  

### **Key Specifications:**  
- **Input Voltage Range:** 4.5V to 38V  
- **Output Voltage Range:** Adjustable from 0.8V to 90% of VIN  
- **Switching Frequency:** 100kHz to 1MHz (adjustable)  
- **Maximum Output Current:** Supports external MOSFETs for high current applications  
- **Control Method:** Voltage mode PWM  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO-8  

### **Features:**  
- **Wide Input Voltage Range:** Suitable for industrial and automotive applications.  
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Overcurrent and Overtemperature Protection:** Enhances system reliability.  
- **Low Dropout Operation:** Maintains regulation even when input voltage is close to output.  

### **Applications:**  
- Industrial power supplies  
- Automotive systems  
- Distributed power architectures  
- Point-of-load (POL) converters  

This information is based on STM's official documentation for the STSR2PMCD-TR.
