- **Current Sensing:** Lossless inductor DCR sensing or resistor sensing  
- **Protection Features:**  
  - Overcurrent protection (OCP)  
  - Overvoltage protection (OVP)  
  - Undervoltage lockout (UVLO)  
  - Thermal shutdown  
- **Intel VR12/IMVP7 Compliance:** Supports dynamic VID (voltage identification) adjustments  
- **Package:** 32-pin VQFN (RHBR)  

### **Applications:**  
- Notebook/desktop CPU/GPU power supplies  
- Server and telecom point-of-load regulators
