Description and Introduction

Dual Synchronous, 400mA/800mA, 2.25MHz Step-Down DC/DC Regulator The LTC3548EDD#PBF is a dual-channel synchronous buck regulator manufactured by Linear Technology (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 2.25V to 5.5V  
- **Output Voltage Range:** 0.6V to 5V (adjustable)  
- **Output Current:** Up to 600mA per channel (1.2A total)  
- **Switching Frequency:** 2.25MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 25µA per channel (50µA total)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead DFN (3mm × 3mm)  

### **Descriptions:**
- The LTC3548EDD#PBF is a high-efficiency, dual-channel synchronous step-down DC/DC converter.  
- It is designed for battery-powered applications, providing two independent regulated outputs.  
- The device operates in Burst Mode® for high efficiency at light loads.  
- It includes internal power switches, synchronous rectification, and soft-start functionality.  

### **Features:**
- **Dual Independent Outputs:** Two 600mA channels with separate control.  
- **Burst Mode Operation:** Enhances efficiency at light loads.  
- **Low Quiescent Current:** 25µA per channel in Burst Mode.  
- **Internal Synchronous Rectification:** Eliminates the need for an external Schottky diode.  
- **Short-Circuit Protection:** Prevents damage during faults.  
- **Thermal Shutdown:** Protects against overheating.  
- **Small Footprint:** 10-Lead DFN package (3mm × 3mm).  

This information is strictly based on the manufacturer's datasheet and technical documentation.
