Description and Introduction

Wide Input Voltage Synchronous Buck-Boost DC/DC Converter The LTC3530EMS is a monolithic synchronous buck-boost DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 1.8V to 5.5V  
- **Output Voltage Range:** 1.8V to 5.25V (adjustable via external resistors)  
- **Output Current:** Up to 500mA  
- **Efficiency:** Up to 95%  
- **Switching Frequency:** 1.5MHz (typical)  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 10-Lead MSOP  

### **Descriptions and Features:**  
- **Buck-Boost Operation:** Seamlessly transitions between buck and boost modes to maintain regulation.  
- **Synchronous Rectification:** Improves efficiency and eliminates the need for an external Schottky diode.  
- **Low Quiescent Current:** 20μA (typical) in Burst Mode operation.  
- **Burst Mode Operation:** Enhances efficiency at light loads.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Power Good Indicator:** Provides a signal when the output is in regulation.  
- **Short-Circuit Protection:** Includes cycle-by-cycle current limiting.  
- **Thermal Shutdown:** Protects the device from overheating.  

This converter is designed for applications requiring regulated power from input sources such as single-cell Li-Ion batteries or other variable power supplies.
