Description and Introduction

Two-Phase Multiphase Buck PWM Controller with Integrated MOSFET Drivers The ISL8101CRZ is a synchronous buck PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 14V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Switching Frequency:** 300kHz (adjustable up to 1MHz)  
- **Maximum Duty Cycle:** 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**
- The ISL8101CRZ is designed for high-efficiency synchronous buck DC-DC converters.  
- It integrates high-side and low-side MOSFET drivers, reducing external component count.  
- Supports voltage-mode PWM control with adjustable switching frequency.  
- Includes features like soft-start, overcurrent protection, and undervoltage lockout (UVLO).  

### **Features:**
- **Adjustable Output Voltage:** Via external resistor divider.  
- **Integrated MOSFET Drivers:** Reduces external components.  
- **Programmable Soft-Start:** Limits inrush current.  
- **Overcurrent Protection (OCP):** Uses lower MOSFET RDS(ON) sensing.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage.  
- **Synchronization Capability:** Can sync with an external clock.  
- **Thermal Shutdown:** Protects against overheating.  

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