Description：

The ISL99390R5935 and ISL99390BR5935 are 90ASmart Power Stages (SPS) that are compatible withRenesas ISL68/69xxx Digital Multiphase (DMP)controllers and phase doublers (ISL6617A),respectively. The ISL99390R5935 andISL99390BR5935 offer best in class current senseaccuracy over line, load, and temperature. Whencombined with a Renesas Digital PWM controller,these devices enable precision system level powermanagement and best in class transient response forloadline based regulators. These devices simplifydesign by eliminating typical DCR sensing networksand associated thermal compensation components.The thermally enhanced 5x6 package enables highdensity designs.The ISL99390R5935 and ISL99390BR5935 featurethe Renesas tri-state PWM input that works withRenesas multiphase PWM controllers and phasedoublers to provide a robust solution in the event ofabnormal operating conditions. The ISL99390R5935and ISL99390BR5935 also improve systemperformance and reliability with integrated faultprotection, including HFET overcurrent, shortedHFET, Smart Reverse Overcurrent (SROCP),Over-Temperature (OTP), and VCC UndervoltageLockout (UVLO).
