### **Descriptions:**  
The LT3494EDDB#PBF is a dual-channel DC/DC converter with internal power switches, designed for high efficiency and compact solutions. It operates in a constant-frequency, current-mode architecture, minimizing external components while providing fast transient response.  

### **Features:**  
- Dual independent step-down regulators  
- Low dropout operation (100% duty cycle)  
- Adjustable switching frequency synchronization  
- Internal compensation  
- Low quiescent current (40µA per channel in shutdown)  
- Small footprint with minimal external components  

This regulator is suitable for applications such as portable devices, automotive systems, and distributed power supplies.
