- **Package:** 28-Lead SSOP  

### **Descriptions:**  
The LTC3735EG#PBF is a high-performance, dual-phase synchronous buck controller designed for high-current applications. It features adaptive voltage positioning, programmable current limiting, and a wide input voltage range, making it suitable for powering microprocessors, FPGAs, and other high-performance digital loads.  

### **Features:**  
- Dual-phase operation for reduced input/output ripple  
- Adaptive voltage positioning for improved transient response  
- Programmable current limit with foldback  
- Adjustable switching frequency (50kHz to 500kHz)  
- Power good output indicator  
- Soft-start and shutdown control  
- Low dropout operation  
- Overvoltage and undervoltage protection  

This controller requires external MOSFETs, inductors, and capacitors to complete the power supply design.
