ISL95869IRTZ-T

Special Purpose Regulators Overview

The ISL95869IRTZ-T is a multi-phase core controller supporting Intel IMVP9 specifications, designed for processor main input rail power. It features two integrated gate drivers and supports an external driver, configurable for 3, 2, or 1 phase operation. The device utilizes Robust Ripple Regulator (R3) modulation technology to achieve faster transient response and variable switching frequencies. Input voltage ranges from +4.5V to +25V with a switch frequency up to 750kHz. Output voltage spans 0.5V to 2.3V. Operating temperature is -10°C to +100°C. Package is 32-lead TQFN (4x4mm).

Special Purpose Regulators Feature Summary

• Supports Intel SVID interface for low-cost communication with CPU.
• Integrates R3 modulation for improved light-load efficiency and transient performance.
• Enables DCR current sensing with NTC thermal compensation.
• Includes adaptive body diode conduction time shortening.

Special Purpose Regulators Applications

• IMVP9 laptop computers
• IMVP9 desktop computers
• IMVP9 tablets and handheld devices

Special Purpose Regulators Procurement Notes

This component is officially marked as obsolete by the manufacturer. Verify availability through authorized distributors or secondary market channels. Confirm RoHS3 compliance and MSL level 3 status before integration. Check for recent PCN updates regarding label changes or assembly modifications.

Special Purpose Regulators Selection Notes

Select this controller for designs requiring Intel IMVP9 compatibility with flexible phase configuration. Ensure system requirements align with the 4.5V to 25V input range and 750kHz maximum frequency. Consider the integrated driver capabilities to reduce external component count compared to discrete solutions.

Special Purpose Regulators Part Context

Part of the Renesas ISL958xx series, specifically the ISL95869 family. Designed under the Robust Ripple Regulator (R3) brand. Shares architectural similarities with other IMVP9 controllers but offers specific integration levels for gate driving.

Special Purpose Regulators Replacement Considerations

No direct public substitute part numbers are confirmed in official documentation. Evaluate compatible IMVP9 controllers from the same manufacturer family if available.
