Renesas Electronics Corporation Special Purpose Regulators ISL6328CRZ-T

The ISL6328CRZ-T is a dual PWM controller designed for powering AMD SVI split-plane processors, featuring two synchronous buck DC/DC converters. It supports 1 or 2-phase operation with internal drivers and 3 or 4-phase operation with external PWM drivers, allowing for configuration flexibility. The device includes advanced features such as precision core voltage regulation with differential remote voltage sensing, achieving ±0.6% system accuracy over temperature. This controller is equipped with a serial VID interface that operates at clock rates up to 3.4MHz and supports Power Savings Mode through phase shedding for improved efficiency at light loads. It also incorporates fully differential, continuous DCR current sensing for accurate load line programming and channel current balancing. The ISL6328CRZ-T provides robust protection mechanisms, including two-level overcurrent protection and multi-tiered overvoltage protection, making it suitable for high-performance applications. The product is housed in a 48-lead QFN package, which aids in reducing the number of external components required, thus offering a compact and cost-effective power management solution.
