Description and Introduction

Dual Monolithic 300mA Synchronous Step-Down Regulator The **LTC3547BEDDB-1#PBF** is a dual 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 600mA per channel (1.2A total)  
- **Switching Frequency:** 2.25MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Lead DFN (3mm x 3mm)  
- **Synchronization:** Yes (external clock)  
- **Low Quiescent Current:** 40μA (per channel)  
- **Power Save Mode:** Yes (for improved light-load efficiency)  
- **Protection Features:** Overcurrent, thermal shutdown  

### **Descriptions:**  
The LTC3547BEDDB-1#PBF is a high-efficiency, dual-channel synchronous buck regulator designed for portable applications. It operates from a single Li-Ion or multi-cell alkaline/NiMH input and provides two independent regulated outputs. The device uses a constant-frequency, current-mode architecture for low noise and fast transient response.  

### **Features:**  
- Dual 600mA synchronous buck regulators  
- 2.25MHz switching frequency (minimizes external components)  
- Low dropout operation (100% duty cycle)  
- Power Save Mode for improved efficiency at light loads  
- Independent enable pins for each channel  
- Soft-start and current limiting  
- Small 10-lead DFN package (3mm x 3mm)
