Description and Introduction

High Efficiency Buck + VLDO Regulator The LTC3541EDD-3#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:** Fixed 3.3V  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1.5MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** DFN-8 (3mm × 3mm)  
- **Synchronous Rectification:** Yes

- **Quiescent Current:** 25µA (typical) in Burst Mode® operation  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The LTC3541EDD-3#PBF is a high-efficiency, synchronous step-down DC/DC converter designed for portable applications. It features a fixed 3.3V output and operates from a single Li-Ion or dual-cell alkaline/NiMH input. The device uses a constant-frequency, current-mode architecture for low noise and fast transient response.  

### **Features:**  
- **Burst Mode® Operation** for high efficiency at light loads  
- **Low Dropout Operation** allows output regulation close to the input voltage  
- **Internal Synchronous Rectification** improves efficiency  
- **Short-Circuit Protection**  
- **Thermal Shutdown**  
- **Soft-Start Function** to limit inrush current  
- **Small DFN-8 Package** for space-constrained applications  

This converter is ideal for battery-powered devices, portable instruments, and other applications requiring a regulated 3.3V supply with high efficiency.
