Description and Introduction

Multi-Phase PWM Controller for Core-Voltage Regulation The ISL6557ACB is a multiphase PWM controller manufactured by Intersil (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Intersil (Renesas Electronics)  
- **Part Number:** ISL6557ACB  
- **Type:** Multiphase PWM Controller  
- **Input Voltage Range:** Typically operates with a 12V supply  
- **Output Voltage Range:** Adjustable, supports low-voltage outputs (e.g., 0.8V to 5V)  
- **Number of Phases:** Configurable for 2-, 3-, or 4-phase operation  
- **Switching Frequency:** Adjustable, typically up to 1MHz per phase  
- **Package:** 32-lead QFN (Quad Flat No-Lead)  

### **Descriptions:**  
- The ISL6557ACB is a high-performance PWM controller designed for voltage regulation in multiphase DC-DC converters.  
- It is commonly used in power supply designs for CPUs, GPUs, and other high-current applications.  
- The controller includes advanced features for precision voltage regulation, fault protection, and dynamic phase management.  

### **Features:**  
- **Precision Voltage Regulation:** Uses a differential remote voltage sense for accurate output control.  
- **Dynamic Phase Management:** Automatically adjusts the number of active phases for efficiency optimization.  
- **Overcurrent Protection:** Includes programmable overcurrent detection and shutdown.  
- **Overvoltage Protection (OVP):** Monitors output voltage and triggers protection if thresholds are exceeded.  
- **Programmable Soft-Start:** Allows controlled ramp-up of output voltage.  
- **Adaptive Delay Matching:** Ensures balanced current sharing between phases.  
- **Thermal Monitoring:** Supports external temperature sensing for thermal protection.
