Description and Introduction

Buck and synchronous rectifier pulse-width modulator (PWM) controller. The ISL6522BCB is a power management IC manufactured by Intersil (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Intersil (now Renesas Electronics)  
- **Part Number:** ISL6522BCB  
- **Package:** 16-Lead QSOP (Quad Flat Small Outline Package)  
- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Switching Frequency:** 300kHz (typical)  
- **Output Current:** Up to 12A (with external MOSFETs)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The ISL6522BCB is a synchronous buck PWM controller designed for high-efficiency voltage regulation.  
- It provides precise control for DC-DC converters, commonly used in power supply applications for motherboards, GPUs, and other computing systems.  
- The IC integrates a high-performance error amplifier, PWM comparator, and MOSFET drivers for synchronous rectification.  

### **Features:**
- **Voltage Mode Control:** Ensures stable and accurate output regulation.  
- **Adjustable Output Voltage:** Configured via external resistor dividers.  
- **Overcurrent Protection (OCP):** Prevents damage due to excessive load conditions.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within the input voltage range.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Synchronous Rectification:** Improves efficiency by reducing power losses.  
- **High-Switch Frequency (300kHz):** Allows for smaller external components.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
