Description and Introduction

Multi-Platform Two-Phase PWM Controller **Manufacturer:** SEMTECH  

**Part Number:** SC2642TSTR  

### **Specifications:**  
- **Type:** Synchronous Buck Converter  
- **Input Voltage Range:** 4.5V to 18V  
- **Output Voltage Range:** Adjustable from 0.6V to 5.5V  
- **Output Current:** Up to 4A  
- **Switching Frequency:** 500kHz to 2.2MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Pin TSSOP  

### **Descriptions:**  
The SC2642TSTR is a high-efficiency, synchronous step-down DC-DC converter designed for a wide range of applications. It integrates low RDS(ON) power MOSFETs to minimize power loss and improve thermal performance.  

### **Features:**  
- Adjustable output voltage  
- High efficiency with integrated MOSFETs  
- Adjustable switching frequency  
- Overcurrent and overtemperature protection  
- Soft-start function  
- Low quiescent current in light-load conditions  
- Power-good indicator  

This information is based on the manufacturer's datasheet. For detailed technical parameters, refer to the official SEMTECH documentation.
