ISL99227BFRZ-TR5783

Overview

The ISL99227BFRZ-TR5783 is a Smart Power Stage (SPS) module from Renesas, integrating high-side and low-side power MOSFETs with gate drivers in a single package. It operates within an input voltage range of 4.5 V to 18 V and delivers up to 60 A output current. The maximum adjustable output voltage is 3.3 V. Designed for surface mount installation, it utilizes a PQFN-32 package. The component functions reliably across an operating temperature range of -40°C to +85°C, with a typical quiescent supply current of 15 mA.

Feature Summary

• Integrates high-accuracy current sensing with integrated temperature compensation for precise load regulation.
• Supports digital control interfaces including SMBus/PMBus v1.3 compatible communication for configuration and monitoring.
• Features comprehensive fault management including pulse-by-pulse phase current limiting and total output current protection.

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 TR5783 against official Renesas documentation to confirm reel quantity and tape specifications. Ensure compatibility with IMVP8 controllers such as the ISL69137. Confirm moisture sensitivity level handling procedures prior to assembly to prevent damage during soldering processes.

Selection Notes

Select this component when designing high-current point-of-load converters requiring integrated power stages. It is suitable for applications needing flexible phase assignment and digital control via PMBus. Verify that the required output current does not exceed 60 A and that the input voltage remains within the 4.5 V to 18 V operational window.

Part Context

This part belongs to the ISL99227 series of Smart Power Stages. It is commonly paired with digital PWM controllers like the ISL69137 to form complete multi-phase voltage regulator modules. The series supports Intel IMVP8 specifications, making it relevant for modern processor power delivery designs.

Replacement Considerations

The ISL99227IRZ-T is a verified substitute within the same product family. Both parts share identical electrical characteristics and pinouts. Verify that the replacement part number matches the required packaging format and suffix specifications for your manufacturing process.
