Description and Introduction

Dual Synchronous 400mA/800mA, 2.25MHz Step-Down DC/DC Regulator The LTC3548AEMSE#PBF is a dual synchronous step-down DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.25V to 5.5V  
- **Output Voltage Range:** 0.6V to VIN (adjustable)  
- **Output Current:** Up to 600mA per channel (1.2A total)  
- **Switching Frequency:** 2.25MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead MSOP  

### **Descriptions:**  
- The LTC3548AEMSE#PBF is a high-efficiency, dual-channel synchronous buck regulator with integrated power switches.  
- It operates from a single Li-Ion or multi-cell alkaline/NiMH input.  
- Features Burst Mode® operation for improved efficiency at light loads.  
- Includes internal compensation, soft-start, and power-good indicators.  

### **Features:**  
- **Dual Independent Outputs:** Two 600mA step-down regulators.  
- **Low Quiescent Current:** 25µA per channel in Burst Mode operation.  
- **Synchronous Rectification:** Improves efficiency and eliminates the need for an external Schottky diode.  
- **Short-Circuit Protection:** Prevents damage during fault conditions.  
- **Small Footprint:** MSOP-10 package for space-constrained applications.  
- **Adjustable Output Voltage:** Set via external resistors.  

This information is based on the manufacturer's datasheet for the LTC3548AEMSE#PBF.
