Overview
The ISL99360FRZ-T, produced by Renesas Electronics America Inc, is a Smart Power Stage (SPS) designed to work in conjunction with Renesas' Digital Multiphase (DMP) controllers and phase doublers. This component is part of the ISL99360 series, which includes the ISL99360 and ISL99360B models. It features integrated high accuracy current and temperature monitors, which can be fed back to the controller to enhance the performance and reliability of multiphase DC/DC systems. The ISL99360FRZ-T simplifies design by eliminating the need for DCR sensing networks and associated thermal compensation, and it supports light-load efficiency through a dedicated low-side FET control pin.
