### **Descriptions:**  
The ISL6535IRZ is a dual PWM controller designed for generating core and chipset supply voltages in desktop and notebook computers. It integrates two synchronous buck PWM controllers with high efficiency and precision voltage regulation.  

### **Features:**  
- Dual PWM controllers for CPU core and chipset power supplies.  
- Adjustable output voltage through external resistors.  
- Integrated MOSFET drivers.  
- Overcurrent protection with programmable current limit.  
- Under-voltage lockout (UVLO) protection.  
- Soft-start functionality for controlled power-up.  
- Fixed-frequency PWM operation (300kHz).  
- Supports synchronous rectification for improved efficiency.  

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