Description and Introduction

Dual 2-Phase, No RSENSE Synchronous Controller for DDR/QDR Memory Termination The LTC3776EUF#PBF is a high-efficiency, synchronous step-down DC/DC controller manufactured by Linear Technology (now part of Analog Devices).  

### **Key Specifications:**  
- **Input Voltage Range:** 4.5V to 38V  
- **Output Voltage Range:** 0.8V to 24V  
- **Switching Frequency:** Adjustable from 50kHz to 900kHz  
- **Maximum Output Current:** Up to 20A (depending on external components)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 28-Lead QFN (5mm x 5mm)  

### **Descriptions and Features:**  
- **Synchronous Operation:** Uses external N-channel MOSFETs for high efficiency.  
- **Wide Input Range:** Supports applications from 4.5V to 38V.  
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Current Mode Control:** Provides fast transient response and stable operation.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Power Good Output:** Monitors output voltage status.  
- **Low Dropout Operation:** Allows 100% duty cycle for low input-output differentials.  
- **Thermal Shutdown:** Protects the IC from overheating.  

This controller is commonly used in industrial, automotive, and telecom applications requiring high-efficiency power conversion.
