### **Specifications:**
- **Input Voltage Range:** 4.5V to 25V
- **Output Voltage Range:** 0.5V to 1.6V (programmable)
- **Number of Phases:** 1 to 4 phases (configurable)
- **Switching Frequency:** 200kHz to 1MHz (adjustable)
- **Duty Cycle Range:** 0% to 100%
- **Operating Temperature Range:** -40°C to +85°C
- **Package Type:** 40-lead QFN (6mm x 6mm)
### **Descriptions:**
The ISL62882 is a high-performance, multi-phase PWM controller designed for VR11/VR11.1-compliant CPU core voltage regulation. It supports dynamic phase shedding to improve efficiency across different load conditions. The controller integrates adaptive voltage positioning (AVP) and provides precise voltage regulation for high-current applications.
### **Features:**
- **Multi-Phase Operation:** Supports 1 to 4 phases with automatic phase shedding.
- **Adaptive Voltage Positioning (AVP):** Enhances transient response and reduces output capacitance.
- **Digital Soft-Start & Soft-Stop:** Prevents inrush current during power-up/down.
- **Overcurrent Protection (OCP):** Monitors and limits output current.
- **Overvoltage Protection (OVP) & Undervoltage Protection (UVP):** Safeguards the system.
- **Programmable Switching Frequency:** Adjustable from 200kHz to 1MHz.
- **Differential Remote Sensing:** Ensures accurate output voltage regulation.
- **Thermal Monitoring:** Includes a temperature sensor for thermal protection.
- **VR11/VR11.1 Compliance:** Supports Intel and AMD processor power requirements.
