ISL6556ACR

Special Purpose Regulators Overview

The ISL6556ACR is a multi-phase VRM10 controller manufactured by Intersil, now part of Renesas. It operates within an input voltage range of 4.75 V to 5.25 V and utilizes pulse width modulation with voltage-mode control. The device is housed in a 28-lead SOIC package measuring 17.9 mm in length. It supports current mode operation alongside standard modes and complies with RoHS standards. The component features a single functional unit with JESD-30 code R-PDSO-G28 and JESD-609 code e3, designed for high-performance voltage regulation applications.

Special Purpose Regulators Feature Summary

• Supports multiphase voltage regulator module (VRM10) architecture
• Capable of operating in both voltage-mode and current-mode control
• Utilizes pulse width modulation technology for precise regulation

Special Purpose Regulators Applications

• Multi-phase CPU core voltage regulation
• High-performance server power supplies
• Graphics processing unit (GPU) power delivery systems

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'CR' against official datasheets to confirm package type and temperature rating distinctions from other variants like 'CBZ'. Ensure the source document explicitly identifies Intersil or Renesas as the manufacturer. Confirm RoHS compliance status and moisture sensitivity level details directly from the component marking or official specification sheet prior to procurement.

Special Purpose Regulators Selection Notes

Select this component when designing multi-phase VRM10 compliant systems requiring flexible control mode options. The 28-lead SOIC package offers a balance between pin count and board space. Verify that the 4.75 V to 5.25 V input range aligns with the system's available power rails. Consider the thermal performance of the SOIC package relative to the expected power dissipation in the target application environment.

Special Purpose Regulators Part Context

The ISL6556 series belongs to Intersil's portfolio of advanced voltage regulator controllers. These devices are engineered for demanding computing applications where stable, efficient power delivery is critical. The AC variant typically denotes a commercial temperature grade. As Intersil was acquired by Renesas Electronics, these parts are supported under the Renesas product line, maintaining compatibility with established design ecosystems.

Special Purpose Regulators Replacement Considerations

The ISL6556ACBZ is a documented alternative within the same family, differing primarily in the package style while retaining similar electrical characteristics. Verify pinout compatibility and thermal requirements before substitution. No other public substitute part numbers are confirmed in the provided data.
