ISL99227BFRZ-T7A

Overview

The ISL99227BFRZ-T7A is a Smart Power Stage (SPS) module from the Renesas ISL99227 series, designed for high-efficiency voltage regulation. It integrates a high-side and low-side power stage with gate drivers into a single PQFN-32 package. The device supports an input voltage range of 4.5 V to 18 V and delivers up to 60 A output current. It features a maximum operating temperature of +85°C and a quiescent current of 15 mA. This component is engineered for applications requiring high density and precision in power delivery.

Feature Summary

• Integrates high-accuracy Smart Power Stage with built-in high-side and low-side MOSFETs
• Supports high-frequency operation for improved transient response and efficiency
• Includes integrated protection mechanisms for robust system reliability

Applications

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

Procurement Notes

Verify the specific suffix 'BFRZ' against official Renesas documentation to confirm pinout and electrical characteristics, as variations exist within the ISL99227 family. Confirm availability status as some variants may be approaching end-of-life. Ensure compatibility with the intended controller IC, such as the ISL69127, for proper system integration.

Selection Notes

Select this component when a compact solution is required for high-current processor power delivery. The integrated SPS design reduces external component count compared to discrete solutions. Verify that the 60 A current rating meets the peak load requirements of the target microprocessor or graphics unit. Ensure the PCB layout supports the thermal dissipation capabilities of the PQFN-32 package.

Part Context

This part belongs to the ISL99227 series of Smart Power Stages manufactured by Renesas Electronics Corporation (formerly Intersil). The series is targeted at demanding computing applications where space and efficiency are critical constraints. The 'T7A' suffix typically indicates tape and reel packaging for automated assembly processes.

Replacement Considerations

Check for direct substitutes within the ISL99227 family, such as the ISL99227IRZ, ensuring pin compatibility. Evaluate newer generations of Renesas SPS modules if available. Verify that any replacement maintains the same 60 A capability and PQFN-32 footprint.
