The ISL6545IRZ is an integrated circuit (IC) component offered by Renesas Electronics. It is a versatile, high-performance power controller specifically designed for multiphase synchronous buck converter applications. This IC can be employed in a wide range of applications, including servers, workstations, and telecom infrastructure.
Key features of the ISL6545IRZ include a high level of integration, providing a complete solution for voltage regulation. It incorporates two PWM (pulse-width modulation) controllers, gate drivers, and a dual-channel MOSFET driver. This integration reduces external component count, simplifies system design, and enhances overall efficiency.
The IC operates with an input voltage ranging from 3V to 5.5V and provides two outputs with a voltage range of 0.8V to 2.5V. Each output can handle a continuous load current of up to 25A, making it suitable for high-power applications. Furthermore, it supports up to six phases in parallel operation, enabling higher output current capability.
A significant advantage of the ISL6545IRZ is its advanced control features. It utilizes a DCR (Digital Current Regulator) sensing technique, enabling highly accurate current sensing and control. This allows for excellent output voltage regulation and precise load sharing between phases, ensuring optimal distribution of the load across multiple power stages
