ISL99227FRZ-T

Overview

The ISL99227FRZ-T is a specialized power management IC (PMIC) from the Renesas Intersil series, designed as a smart power stage module. It operates within an input voltage range of 4.5 V to 18 V and delivers a maximum output current of 60 A. The device functions efficiently across a temperature range of -40°C to +125°C and features a PQFN-32 surface-mount package. With a power dissipation rating of 12.5 W and quiescent currents of 4.75 mA or 15 mA at a 5 V supply, it supports high-density point-of-load (POL) DC/DC conversion for demanding computing environments.

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm exact tape-and-reel quantities and handling specifications. Ensure compatibility with the intended PCB footprint, specifically the PQFN-32 package dimensions. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity before finalizing procurement orders.

Selection Notes

Select this component when designing high-current power stages requiring integrated switching elements. The 60 A output capability suits dense server and graphics applications. Verify that the 4.5 V to 18 V input range aligns with the system bus voltage. Consider the PQFN-32 package size for thermal management strategies in confined spaces.

Part Context

This component belongs to the ISL99227 series of smart power stage modules manufactured by Renesas Electronics Corporation under its former Intersil brand. These devices are engineered to work in conjunction with multi-phase PWM controllers to enhance overall power system performance and reliability in high-performance computing architectures.

Replacement Considerations

Consult official Renesas substitution guides for verified equivalents. Generic cross-references may not match the specific smart power stage integration or thermal characteristics required for high-density server and graphics regulator designs.
