Renesas has developed a full range of power stages supporting various current ratings to meet any ASIC, SOC, FPGA, or graphic card power rail requirements. When designing with Renesas multiphase controllers, the ISL99227 60 A Smart Power Stage is an excellent companion. Unlike competing solutions that support a 20 V lateral FET process that poses a reliability risk, especially in key server and telecom applications, the ISL99227 Smart Power Stage supports a 25 V trench FET design to deliver immunity to voltage spikes and mitigate avalanche conditions. The large copper pads for ground and VIN result in low thermal resistance compared with competing monolithic designs that support flip chip on lead packages. The dual side cooling package coupled in a proprietary 5 mm x 5 mm package, designed to minimize packaging parasitics, delivers excellent efficiency across the full load, thus making it ideal for high current applications such as servers and infrastructure power. With integrated current and temperature sense reporting, and with 3% accuracy over line, load, and temperature, the ISL99227 simplifies the powertrain design by eliminating complex DCR networks and delivering a compact power solution for space constrained designs.
