Description and Introduction

500mA, 2.25MHz Synchronous Step-Down DC/DC Converter The LTC3542EDC is a high-efficiency, 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 300mA  
- **Switching Frequency:** 1.5MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 25µA (typical) in Burst Mode® operation  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 6-Lead DFN (2mm × 2mm)  

### **Descriptions:**  
- The LTC3542EDC is a compact, high-efficiency step-down converter designed for portable applications.  
- It features Burst Mode® operation for improved efficiency at light loads.  
- The device includes internal synchronous rectification, eliminating the need for an external Schottky diode.  
- It is suitable for battery-powered devices, handheld instruments, and other space-constrained applications.  

### **Features:**  
- **Synchronous Operation:** High efficiency with integrated power switches.  
- **Burst Mode® Operation:** Reduces quiescent current for longer battery life.  
- **Low Dropout Operation:** Allows 100% duty cycle for maximum output voltage.  
- **Internal Soft-Start:** Prevents inrush current at startup.  
- **Short-Circuit Protection:** Enhances reliability.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Small Footprint:** DFN package saves board space.
