Description and Introduction

Multi-Phase PWM Controller The ISL6244CR is a dual-phase, synchronous buck PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 5.5V to 28V  
- **Output Voltage Range:** Adjustable down to 0.7V  
- **Switching Frequency:** Adjustable from 200kHz to 1MHz  
- **Maximum Duty Cycle:** Up to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Lead QFN (Quad Flat No-Lead)  

### **Descriptions:**
- The ISL6244CR is designed for high-efficiency, dual-phase DC-DC conversion in notebook computers, servers, and other power supply applications.  
- It supports two-phase operation with current sharing for improved thermal performance and reduced input/output ripple.  
- Includes adaptive voltage positioning (AVP) to optimize transient response.  

### **Features:**
- **Dual-Phase Operation:** Enhances efficiency and reduces component stress.  
- **Programmable Switching Frequency:** Adjustable from 200kHz to 1MHz.  
- **Adaptive Voltage Positioning (AVP):** Improves transient response.  
- **Integrated MOSFET Drivers:** Supports N-channel power MOSFETs.  
- **Overcurrent Protection (OCP):** Prevents damage during excessive load conditions.  
- **Overvoltage Protection (OVP):** Safeguards against output voltage spikes.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Power-Good Output:** Monitors output voltage status.  

This information is based on the manufacturer's datasheet for the ISL6244CR.
