ISL6455AIRZS2698

Special Purpose Regulators Overview

The ISL6455AIRZS2698 is a triple output power management IC designed for FPGA applications. It integrates one 0.6A PWM regulator and two 0.3A LDOs. The input voltage range is 4.2V to 5.5V. Output voltages range from 0.8V to 3.3V. It operates between -40°C and +85°C. The device is housed in a 24-pin QFN package with an exposed pad.

Special Purpose Regulators Feature Summary

• Integrates a high-current PWM step-down converter alongside dual low-dropout linear regulators for comprehensive power delivery.

Special Purpose Regulators Applications

• FPGA power supply systems
• Programmable logic device biasing

Special Purpose Regulators Procurement Notes

Verify component status as obsolete. Confirm manufacturer lineage from Intersil to Renesas Electronics Corporation. Ensure the specific suffix matches required packaging or temperature grades if sourcing alternatives. Validate RoHS compliance status against current inventory requirements.

Special Purpose Regulators Selection Notes

Select this component when a single-chip solution for FPGA core, I/O, and auxiliary rails is required. The integrated topology reduces board space compared to discrete solutions. Verify that the combined current capabilities of the PWM and LDO outputs meet the specific load requirements of the target logic device.

Special Purpose Regulators Part Context

This part belongs to the ISL6455 family of specialized regulators. It is manufactured by Renesas Electronics Corporation, following Intersil's acquisition. The series targets complex digital logic requiring multiple stable voltage domains from a single input source.

Special Purpose Regulators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-compatible replacements require independent verification against current Renesas portfolios.
