Description and Introduction

Triple 800mA Synchronous Step-Down Regulator The LTC3545EUD#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 600mA  
- **Switching Frequency:** 2.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead QFN (3mm × 3mm)  
- **Features:**  
  - Synchronous rectification  
  - Low quiescent current (30µA typical)  
  - Burst Mode® operation for improved efficiency at light loads  
  - Internal soft-start  
  - Overcurrent and thermal protection  
  - Power good indicator  

### **Descriptions and Features:**  
The LTC3545EUD#PBF is a high-efficiency, monolithic synchronous buck regulator designed for portable applications. It operates from a 2.5V to 5.5V input range and delivers up to 600mA of output current. The device uses a constant-frequency, current-mode architecture for stable operation and fast transient response.  

Key features include Burst Mode operation for improved efficiency at light loads, internal compensation, and a power good indicator. The compact QFN package makes it suitable for space-constrained applications such as handheld devices, portable instruments, and wireless modules.  

This IC is ideal for battery-powered systems requiring high efficiency and a small footprint.
