Renesas Electronics ISL99390FRZ 90A Smart Power Stage (SPS) Module
Renesas Electronics ISL99390FRZ 90A Smart Power Stage (SPS) Module is compatible with the ISL68/69xxx Digital Multiphase (DMP) controllers and phase doublers (ISL6617A), respectively. The 90A SPS provides excellent current sense accuracy over line, load, and temperature. Combining a Renesas Digital PWM controller with the SPS allows precision system-level power management and efficient transient response for loadline-based regulators. The devices simplify design by eliminating typical DCR sensing networks and associated thermal compensation components.
The Renesas ISL99390FRZ 90A SPS Module is available in a thermally enhanced 5x6 package, creating high-density designs.
The ISL99390FRZ features the tri-state PWM input that functions with multiphase PWM controllers and phase doublers to equip a robust solution in the event of abnormal operating conditions. The device also improves system performance and reliability with integrated fault protection, including HFET overcurrent, shorted HFET, Smart Reverse Overcurrent (SROCP), Over-Temperature (OTP), and VCC Undervoltage Lockout (UVLO).
