Description and Introduction

PROGRAMMABLE SYNCHRONOUS DC/DC CONTROLLER FOR ADVANCED PROCESSORS **Manufacturer:** ON Semiconductor  
**Part Number:** SC1158CS  

### **Specifications:**  
- **Output Voltage:** Adjustable (via external resistors)  
- **Output Current:** Up to 3A  
- **Input Voltage Range:** 4.5V to 18V  
- **Switching Frequency:** 300kHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-16 (Surface Mount)  

### **Descriptions:**  
The SC1158CS is a synchronous buck regulator designed for high-efficiency DC-DC conversion. It integrates high-side and low-side MOSFETs, reducing external component count. The device supports adjustable output voltage and provides protection features such as overcurrent and thermal shutdown.  

### **Features:**  
- Integrated high-side and low-side MOSFETs  
- Adjustable output voltage  
- High efficiency (up to 95%)  
- Overcurrent protection  
- Thermal shutdown protection  
- Soft-start function  
- Synchronous rectification for improved efficiency  
- Low dropout operation  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application circuits, refer to the official documentation.
