### **Descriptions:**  
The TPS23770PWPR is a high-efficiency PoE PD controller with an integrated DC-DC converter. It is designed for IEEE 802.3at-compliant applications, providing power management for PoE-powered devices such as IP cameras, wireless access points, and VoIP phones.  

### **Features:**  
- **Integrated PD Interface and DC-DC Controller**  
- **Supports High-Power PoE+ Applications (up to 25.5W)**  
- **Programmable Inrush Current Limit**  
- **Low Standby Power Consumption**  
- **Wide Input Voltage Range**  
- **Robust Protection Features (Overcurrent, Thermal Shutdown, UVLO)**  
- **PowerPAD™ Package for Enhanced Thermal Performance**  

This device simplifies PoE system design by combining PD detection, classification, and DC-DC conversion in a single IC.
