Description and Introduction

Single-Phase PWM Regulator for IMVP-6.5? Mobile CPUs and GPUs The ISL62881HRTZ is a power management IC manufactured by INTERSIL (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features from the available knowledge base:  

### **Specifications:**  
- **Manufacturer:** INTERSIL (now Renesas Electronics)  
- **Part Number:** ISL62881HRTZ  
- **Package:** 40-Lead QFN (6x6 mm)  
- **Input Voltage Range:** 4.5V to 25V  
- **Output Voltage Range:** Adjustable (supports VR11, VR10.x, and IMVP-6+ standards)  
- **Number of Phases:** 1 to 4 phases (configurable)  
- **Switching Frequency:** Adjustable (250kHz to 1MHz)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The ISL62881HRTZ is a multi-phase PWM controller designed for high-performance voltage regulation in CPU and GPU power supplies. It supports Intel® IMVP-6+ and AMD SVI specifications, enabling precise voltage control for modern processors.  

### **Features:**  
- **Digital Multi-Phase PWM Controller:** Supports 1 to 4 phases for scalable power delivery.  
- **Adaptive Voltage Positioning (AVP):** Enhances transient response and reduces output capacitance.  
- **Dynamic Phase Shedding:** Improves efficiency at light loads by disabling unused phases.  
- **Programmable Switching Frequency:** Adjustable from 250kHz to 1MHz.  
- **Integrated MOSFET Drivers:** Supports N-channel power MOSFETs.  
- **Differential Remote Voltage Sensing:** Ensures accurate voltage regulation.  
- **Overcurrent, Overvoltage, and Undervoltage Protection:** Built-in safeguards for system reliability.  
- **Serial VID (SVID) Interface:** Compatible with Intel® IMVP-6+ and AMD SVI standards.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application notes, refer to the official datasheet.
