### **Descriptions:**  
The LTC3543EDCB#PBF is a high-efficiency, synchronous buck-boost DC/DC converter designed for applications requiring a regulated output voltage from an input supply that can be above, below, or equal to the output voltage. It is suitable for battery-powered devices, portable electronics, and other power-sensitive applications.  

### **Features:**  
- **Buck-Boost Operation:** Seamlessly transitions between buck and boost modes.  
- **Low Quiescent Current:** 30µA (typical) in Burst Mode operation.  
- **Synchronous Rectification:** Improves efficiency and reduces external component count.  
- **Burst Mode Operation:** Enhances light-load efficiency.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Thermal Shutdown Protection:** Safeguards against overheating.  
- **Small Footprint:** DFN package for space-constrained applications.
