Description and Introduction

Dual Mobile-Friendly PWM Controller with DDR Option The ISL6227HRZ is a dual synchronous buck PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 25V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Output Current:** Supports dual outputs (each capable of high current with external MOSFETs)  
- **Efficiency:** Up to 95% (depends on external components)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-Lead QFN (5x5mm)  

### **Descriptions:**  
- The ISL6227HRZ is a high-performance, dual-output PWM controller designed for synchronous buck DC-DC converters.  
- It provides precise voltage regulation for applications such as notebooks, desktops, and embedded systems.  
- The device includes integrated gate drivers for N-channel MOSFETs and supports adjustable soft-start.  

### **Features:**  
- **Dual Independent PWM Controllers** for two output rails.  
- **Adjustable Switching Frequency** (300kHz to 1MHz).  
- **Integrated MOSFET Drivers** (up to 2A gate drive current).  
- **Programmable Soft-Start** for controlled power-up sequencing.  
- **Overcurrent Protection (OCP)** with hiccup mode.  
- **Overvoltage Protection (OVP)** and undervoltage lockout (UVLO).  
- **Power-Good (PGOOD) Output** for each channel.  
- **Synchronous Rectification** for improved efficiency.  
- **Differential Remote Sensing** for accurate voltage regulation.  

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