ISL9307IRTAANCZ-T

Overview

The ISL9307IRTAANCZ-T is a switching regulator component manufactured by Renesas Electronics Corporation, formerly Intersil. It functions as a dual DC/DC converter with an integrated LDO, designed for applications requiring multiple power rails from a single input source. The device features adjustable output voltages and is housed in a TQFN L16 package. This specific part number variant is identified as obsolete or end-of-life status within the manufacturer's product lifecycle.

Feature Summary

• Dual DC/DC converter architecture providing independent power regulation channels
• Integrated low-dropout regulator (LDO) for auxiliary power supply needs
• Adjustable output voltage configuration for flexible system design

Applications

• Portable electronic devices requiring multi-rail power distribution
• Embedded systems utilizing compact surface-mount packaging
• Applications necessitating combined switching and linear regulation topologies

Procurement Notes

Verify current availability through authorized distributors, as this component is listed as obsolete. Confirm exact suffix compatibility for tape-and-reel quantities if sourcing from secondary markets. Ensure datasheet revisions match design requirements before integration into new production cycles.

Selection Notes

Evaluate alternative components from the RAA48930x series or similar synchronous buck controllers for modern designs. Consider updated packages and efficiency improvements available in newer Renesas power management portfolios. Assess pin-to-pin compatibility if replacing existing legacy designs with current generation parts.

Part Context

This component belongs to the broader family of power management ICs produced by Renesas Electronics. It represents legacy technology from the Intersil acquisition era, focusing on compact multi-output solutions. The TQFN L16 package indicates a small form factor suitable for space-constrained portable electronics and industrial control modules.

Replacement Considerations

Consult Renesas official cross-reference tools for direct substitutes. The RAA48930x series offers comparable functionality with improved efficiency. Verify electrical specifications and thermal performance when transitioning to newer active components.
