Description and Introduction

Multi-Phase PWM Controller The ISL6559CR-T is a PWM controller manufactured by Intersil (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Intersil (now Renesas Electronics)  

### **Part Number:**  
ISL6559CR-T  

### **Description:**  
The ISL6559CR-T is a high-performance, multi-phase PWM controller designed for precision voltage regulation in power supplies, particularly for microprocessors and other DC-DC applications.  

### **Key Features:**  
- **Multi-Phase PWM Control:** Supports 2 to 4-phase operation for high-current applications.  
- **Precision Voltage Regulation:** ±0.5% system accuracy over temperature.  
- **Adaptive Phase Control:** Automatically adjusts the number of active phases for optimal efficiency.  
- **Programmable Switching Frequency:** Allows flexibility in design.  
- **Overcurrent Protection:** Monitors and protects against excessive current.  
- **Overvoltage Protection (OVP):** Safeguards the load from voltage spikes.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Differential Remote Voltage Sensing:** Compensates for PCB trace resistance.  
- **Thermal Monitoring:** Includes thermal shutdown for safety.  

### **Applications:**  
- Voltage regulator modules (VRMs)  
- High-current DC-DC converters  
- Server and desktop motherboard power supplies  
- Workstation and gaming system power management  

### **Package:**  
- **Type:** 28-Lead QSOP (Quarter Small Outline Package)  
- **Mounting:** Surface Mount
