Description and Introduction

Microprocessor CORE Voltage Regulator Two-Phase Buck PWM Controller The ISL6560CB-T is a PWM controller manufactured by Intersil (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Intersil (Renesas Electronics)  
- **Part Number:** ISL6560CB-T  
- **Type:** Multi-Phase PWM Controller  
- **Input Voltage Range:** 4.5V to 12V  
- **Output Voltage Range:** Adjustable (typically 0.8V to 5.5V)  
- **Number of Phases:** 1, 2, or 3-phase operation  
- **Switching Frequency:** Adjustable (100kHz to 1MHz)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Lead SOIC  

### **Descriptions:**
The ISL6560CB-T is a high-performance, multi-phase PWM controller designed for voltage regulator modules (VRMs) and DC-DC converters. It supports single, dual, or three-phase operation, providing precise voltage regulation for high-current applications such as CPUs and GPUs. The device integrates advanced control features, including adaptive voltage positioning (AVP) and overcurrent protection.

### **Features:**
- **Multi-Phase Operation:** Supports 1, 2, or 3-phase configurations.  
- **Precision Voltage Regulation:** ±1% system accuracy over temperature.  
- **Adaptive Voltage Positioning (AVP):** Enhances transient response.  
- **Programmable Switching Frequency:** 100kHz to 1MHz.  
- **Overcurrent Protection:** Uses MOSFET RDS(ON) sensing.  
- **Power-Good Output:** Monitors output voltage status.  
- **Soft-Start Function:** Controlled startup to reduce inrush current.  
- **Differential Remote Sensing:** Compensates for PCB trace losses.  
- **Adjustable Dead-Time Control:** Optimizes efficiency.  

This information is based solely on the manufacturer’s datasheet and technical documentation.
