Description and Introduction

1.8A, 4MHz, Synchronous Step-Down DC/DC Converter The LTC3568EDD#PBF is a synchronous step-down DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.6V to VIN  
- **Output Current:** Up to 800mA  
- **Switching Frequency:** 1.5MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead DFN (3mm × 3mm)  
- **Synchronous Rectification:** Yes  
- **Low Quiescent Current:** 25µA (typical)  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The LTC3568EDD#PBF is a high-efficiency, monolithic synchronous buck regulator that operates from a single Li-Ion or multi-cell alkaline/NiMH input. It uses a constant-frequency, current-mode architecture and integrates power switches to minimize external components.  

### **Features:**  
- **Burst Mode® Operation** for improved efficiency at light loads  
- **Internal Soft-Start** to reduce inrush current  
- **Short-Circuit Protection**  
- **Thermal Shutdown**  
- **Low Dropout Operation** (100% duty cycle)  
- **Adjustable Output Voltage** via external resistors  
- **Synchronizable to External Clock**  

This device is suitable for portable applications requiring high efficiency and compact size.
