ISL6225CA-T

Special Purpose Regulators Overview

The ISL6225CA-T is a specialized power management integrated circuit manufactured by Renesas Electronics Corporation, formerly Intersil. It functions as a dual-output controller specifically designed for regulating DDR and SDRAM memory applications. The device operates with an input voltage range of 5V to 24V and provides adjustable output voltages between 0.9V and 5.5V. It is housed in a 28-SSOP/QSOP surface-mount package and supports an operating temperature range from -10°C to +85°C. This component is classified as a special-purpose regulator intended for high-density memory power systems.

Special Purpose Regulators Feature Summary

• Dual-output architecture optimized for simultaneous regulation of multiple memory rails
• Integrated control logic tailored for DDR and SDRAM power sequencing requirements
• Wide input voltage tolerance supporting standard intermediate bus architectures

Special Purpose Regulators Applications

• DDR DRAM power supply regulation
• SDRAM memory module voltage control
• Computer motherboard memory subsystems

Special Purpose Regulators Procurement Notes

Verify the current lifecycle status before design implementation, as this specific part number is listed as obsolete or discontinued by the manufacturer. Confirm that any available stock matches the exact suffix designation to ensure correct packaging and pinout compatibility. Cross-reference with official Renesas legacy documentation to validate technical specifications against potential replacement components.

Special Purpose Regulators Selection Notes

Select this component only if the design explicitly requires the specific control characteristics and pin configuration of the ISL6225 family for DDR/SDRAM applications. Evaluate whether newer Renesas PMIC solutions offer equivalent functionality with improved availability. Ensure the thermal and electrical requirements of the target system align with the device's specified operating limits and package constraints.

Special Purpose Regulators Part Context

This component belongs to the Intersil (now Renesas) portfolio of specialized power management ICs. The company was acquired by Renesas Electronics, integrating its analog and mixed-signal technologies into broader industrial and automotive product lines. The ISL6225 series represents legacy designs focused on memory power delivery, now maintained within Renesas's historical product catalog for existing equipment maintenance.

Special Purpose Regulators Replacement Considerations

Consult Renesas Electronics Product Legacy Documents for officially confirmed substitute part numbers. Verify functional equivalence regarding pinouts and control logic before transitioning to alternative components.
