Description and Introduction

Low IQ, Dual 2-Phase Synchronous Step-Down Controller The LTC3868EUFD-1#PBF is a high-performance synchronous step-down DC/DC controller manufactured by **Linear Technology** (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 38V  
- **Output Voltage Range:** 0.6V to 5.5V  
- **Switching Frequency:** Adjustable from 200kHz to 2MHz  
- **Maximum Output Current:** Up to 20A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 28-Lead QFN (5mm x 5mm)  
- **Control Method:** Constant-frequency current-mode control  
- **Features:**  
  - Adjustable soft-start  
  - Power Good output  
  - External synchronization capability  
  - Low shutdown current (<1µA)  
  - Overcurrent and overtemperature protection  

### **Descriptions:**  
The LTC3868EUFD-1#PBF is designed for high-efficiency step-down power conversion in applications such as industrial, automotive, and telecom systems. It supports **PolyPhase® operation** for multi-phase configurations, reducing input and output ripple.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4.5V to 38V operation.  
- **High Efficiency:** Minimizes power loss with synchronous rectification.  
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Robust Protection:** Includes overcurrent, overtemperature, and undervoltage lockout (UVLO).  
- **PolyPhase Capable:** Enables multi-phase operation for high-current applications.  

This controller is ideal for systems requiring high power density and efficiency.
