SPS Pmic Power Management Integrated Circuit 90A ISL99390FRZ 90A Smart Power Stages

Power Management ICs ISL99390FRZ 90A Smart Power Stage (SPS) Gen2 Module

Description

The ISL99390FRZ is 90A Smart Power Stages (SPS) that are compatible with Renesas ISL68/69xxx Digital Multiphase (DMP) controllers and phase doublers(ISL6617A),respectively. The ISL99390FRZ offer best in class current sense accuracy over line, load, and temperature. When combined with a Renesas Digital PWM controller,these devices enable precision system level power management and best in class transient response for loadline based regulators. These devices simplify design by eliminating typical DCR sensing networks and associated thermal compensation components.The thermally enhanced 5x6 package enables high density designs.
