ISL8101IRZ

Special Purpose Regulators Overview

The ISL8101IRZ is a two-phase multiphase buck PWM controller manufactured by Intersil, now part of Renesas Electronics. It features integrated MOSFET drivers for high-efficiency power conversion. The device operates within an ambient temperature range of -40°C to +85°C and is housed in a 24-lead QFN package measuring 4x4 mm. It supports Intel VRM9, VRM10, and AMD Hammer voltage regulator applications.

Special Purpose Regulators Feature Summary

• Integrates dual MOSFET drivers to reduce external component count
• Supports multiphase buck topology for improved current sharing
• Compatible with major processor voltage regulator standards

Special Purpose Regulators Applications

• Intel VRM9 compliant systems
• Intel VRM10 compliant systems
• AMD Hammer platform voltage regulation

Special Purpose Regulators Procurement Notes

Verify the specific suffix (e.g., IRZ vs IR33Z) against the design schematic, as packaging and lead-free status may vary. Confirm availability through authorized Renesas channels, as this component may be subject to limited supply or end-of-life restrictions. Ensure the supplier provides valid traceability documentation for quality assurance.

Special Purpose Regulators Selection Notes

Select this controller for designs requiring a compact two-phase solution with integrated gate drivers. Verify that the input voltage range and load requirements align with the datasheet specifications. Consider thermal performance within the 4x4mm QFN footprint when designing the PCB layout for adequate heat dissipation.

Special Purpose Regulators Part Context

This component belongs to the Intersil ISL8101 series of multiphase controllers. Following Renesas Electronics' acquisition of Intersil, these products are managed under the Renesas portfolio. The ISL8101IRZ specifically targets desktop and server processor power delivery applications requiring high transient response.

Special Purpose Regulators Replacement Considerations

Check Renesas Product Legacy Documents for officially confirmed substitute part numbers. Do not assume functional equivalence with other Intersil models without verifying pinout and electrical parameter compatibility.
