Description and Introduction

PWM buck DC-DC and triple linear power controller. The ISL6521CBZ is a power management IC manufactured by **INTERSIL** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Intersil (Renesas)  
- **Package:** 16-pin SOIC (CBZ)  
- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Switching Frequency:** Up to 1MHz  
- **Output Current:** Supports dual synchronous buck regulators  
- **Efficiency:** High efficiency due to synchronous rectification  
- **Protection Features:** Overcurrent protection (OCP), undervoltage lockout (UVLO), and thermal shutdown  

### **Descriptions:**  
The ISL6521CBZ is a **dual synchronous buck PWM controller** designed for generating regulated voltages in high-performance applications. It provides precise voltage regulation for microprocessors, GPUs, and other digital ICs. The IC integrates control, monitoring, and protection functions for reliable power supply designs.  

### **Features:**  
- **Dual PWM Controllers:** Independently controls two synchronous buck regulators.  
- **Adjustable Output Voltage:** Configured via external feedback resistors.  
- **High Switching Frequency:** Up to 1MHz for compact power supply designs.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Programmable Soft-Start:** Prevents inrush current during startup.  
- **Power-Good Output:** Monitors regulator status.  
- **Overcurrent Protection (OCP):** Safeguards against excessive load currents.  
- **Thermal Shutdown:** Prevents overheating damage.  

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