ISL99227BFRZ-T

Overview

The ISL99227BFRZ-T is a Smart Power Stage (SPS) module from Renesas, integrating high-accuracy control with power switching components. It operates within an input voltage range of 4.5 V to 18 V and delivers up to 60 A output current. The device supports a maximum output voltage of 3.3 V and functions reliably between -40°C and +85°C. With a quiescent current of 15 mA, it utilizes a PQFN-32 package for surface mount installation.

Feature Summary

• Integrates driver and power FETs into a single compact Smart Power Stage module
• Provides high-accuracy current sensing capabilities for precise load regulation
• Includes comprehensive protection features such as overcurrent, thermal shutdown, and undervoltage lockout

Applications

• Core, Graphic, and Memory Regulators for Microprocessors
• High Frequency and High Efficiency VRM and VRD Systems
• High Density Voltage Regulators for Server, Networking, and Cloud Computing
• POL DC/DC Converters and Video Gaming Consoles

Procurement Notes

Verify the specific suffix 'BF' against official Renesas documentation to confirm exact binning or temperature grade variations. Confirm RoHS compliance status through the manufacturer's datasheet. Ensure the PQFN-32 footprint matches your PCB design constraints before ordering.

Selection Notes

Select this component when designing point-of-load converters requiring high current density and integrated gate drive. The 60 A capability suits demanding processor core loads. Evaluate thermal performance requirements given the 12.5 W power dissipation rating in the specified operating temperature range.
