Description and Introduction

500mA, 2.25MHz Synchronous Step-Down DC/DC Converter The LTC3542IS6#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:** 0.6V to VIN  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 2.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6  
- **Features:**  
  - Synchronous rectification for high efficiency  
  - Low quiescent current (25µA in Burst Mode® operation)  
  - Internal soft-start  
  - Current mode control for fast transient response  
  - Short-circuit protection  
  - Thermal shutdown protection  

### **Descriptions:**  
The LTC3542IS6#PBF is a high-efficiency, monolithic synchronous buck regulator designed for portable applications. It operates from a single Li-Ion cell or other low-voltage sources. The device uses a constant-frequency, current-mode architecture for stable operation across a wide range of loads.  

### **Features:**  
- **Burst Mode® Operation:** Reduces quiescent current for improved efficiency at light loads.  
- **Low Dropout Operation:** Allows 100% duty cycle for maximum output voltage.  
- **Small Footprint:** SOT-23-6 package is ideal for space-constrained applications.  
- **No Schottky Diode Required:** Integrated power switches eliminate the need for an external diode.  
- **Fixed Frequency Operation:** Minimizes noise and simplifies filtering.  

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