Partnumber Manufacturer Quantity Availability
ISL6568 1119 In Stock

Description and Introduction

Two-Phase Buck PWM Controller with Integrated MOSFET Drivers for VRM9, VRM10, and AMD Hammer Applications The ISL6568 is a single-phase PWM controller manufactured by Intersil (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 12V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** Adjustable up to 1MHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 16-Lead QSOP (Quad Flat Small Outline Package)  

### **Descriptions:**  
- The ISL6568 is a high-performance, single-phase synchronous buck PWM controller designed for voltage regulator applications.  
- It supports precision voltage regulation for microprocessors and other low-voltage DC-DC converters.  
- The controller integrates MOSFET drivers and provides adaptive voltage positioning (AVP) for improved transient response.  

### **Features:**  
- **Precision Voltage Regulation:** ±1% system accuracy over temperature.  
- **Adaptive Voltage Positioning (AVP):** Enhances transient response and reduces output capacitance.  
- **Programmable Switching Frequency:** Up to 1MHz for optimized efficiency and component size.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Overcurrent Protection:** Uses MOSFET RDS(ON) sensing for accurate current limiting.  
- **Power-Good Output:** Monitors output voltage status.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Differential Remote Sensing:** Compensates for PCB trace resistance.
