Quality Control: Learn More
The Intersil ISL6244HRZ is a 4-phase, voltage-mode PWM DC-DC step-down controller. This switching controller utilizes a proprietary PWM control scheme to deliver high efficiency and excellent transient response. It features a wide switching frequency range from 80kHz to 1MHz, with adjustable frequency control. The device supports a maximum duty cycle of 75% and provides four positive output phases. Integrated control features include Enable and Power Good signals. Designed for surface mount applications, the ISL6244HRZ is supplied in a 32-QFN (5x5) exposed pad package and operates within an ambient temperature range of -10°C to 100°C. This component is commonly utilized in computing, server, and high-performance power supply applications.
