ISL99390R5935, ISL99390BR5935
90A Smart Power Stage (SPS) Module with Integrated High Accuracy Current
and Temperature Monitors
The ISL99390R5935 and ISL99390BR5935 are 90A
Smart Power Stages (SPS) that are compatible with
Renesas ISL68/69xxx Digital Multiphase (DMP)
Features
• VIN input range: +3.0V to +16V
• Supports 90A DC current
controllers and phase doublers (ISL6617A),
respectively. The ISL99390R5935 and
• 3.3V compatible tri-state PWM input
(ISL99390R5935)
ISL99390BR5935 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.
• 5V compatible tri-state PWM input
(ISL99390BR5935)
• ±3% accuracy continuous signal for current monitor
• 8mV/°C temperature monitor, TOUT
• Comprehensive fault protection for high system
reliability
○ High-side FET short and overcurrent protection
○ Smart Reverse Overcurrent Protection (SROCP)
○ Over-temperature protection
The ISL99390R5935 and ISL99390BR5935 feature
the Renesas tri-state PWM input that works with
Renesas multiphase PWM controllers and phase
doublers to provide a robust solution in the event of
abnormal operating conditions. The ISL99390R5935
and ISL99390BR5935 also improve 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).
○ VCC Undervoltage Lockout (UVLO)
• Enable Input and fault reporting outputs
• Low power mode operation
• Up to 1.25MHz switching frequency
• RoHS-compliant, 5x6 QFN package
Applications
• Accelerators (GPU, ASIC, Artificial Intelligence)
• Core, graphic, and memory VRs for microprocessors
• High density VR for server, networking, and cloud
computing
• POL DC/DC converters and video gaming consoles
