Renesas Electronics Corporation Special Purpose Regulators ISL6313CRZ-T

The ISL6313CRZ-T is a two-phase PWM controller designed for precision voltage regulation in advanced microprocessor applications, compatible with both Intel VR11 and AMD processors. It features integrated MOSFET drivers, allowing for a compact design that reduces the need for external components. The controller supports adjustable reference voltage offsets and provides differential remote voltage sensing with a system accuracy of ±0.5% over temperature. Key functionalities include active pulse positioning modulation for optimal transient response, adaptive phase alignment, and fully differential continuous DCR current sensing. The device also incorporates programmable current sense resistors, dynamic VID technology, and multiple protection features, including overcurrent and overvoltage protection. The ISL6313CRZ-T operates at selectable frequencies up to 1.5MHz per phase and is packaged in a 36-lead TQFN format, making it suitable for space-constrained applications.
