Description and Introduction

Dual Synchronous Buck Regulator Controller The LM2647MTCX is a dual synchronous buck regulator manufactured by National Semiconductor (NSC). It is designed to provide two independent step-down DC-DC conversions with high efficiency.  

### **Key Specifications:**  
- **Input Voltage Range:** 3V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 2A per channel  
- **Switching Frequency:** 1.5MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 28-pin TSSOP (MTCX)  

### **Features:**  
- Dual synchronous PWM buck regulators  
- Integrated power MOSFETs  
- Adjustable soft-start  
- Power-good output for each regulator  
- Current-mode control for fast transient response  
- Overcurrent and thermal protection  
- Low shutdown current (<1µA)  

This regulator is commonly used in portable devices, networking equipment, and other applications requiring efficient dual voltage regulation.
