ISL9307IRTAANLZ-T7A

Overview

The ISL9307IRTAANLZ-T7A is a quad-output power management integrated circuit manufactured by Renesas Electronics. It integrates two synchronous buck converters and two low-dropout linear regulators within a single package. The device operates with an input voltage range of 1.5V to 5.5V and supports switching frequencies up to 3MHz. Outputs are configurable, providing adjustable voltages for the DC/DC channels and fixed or adjustable levels for LDOs. It is housed in a compact 16-TQFN (4x4mm) package with an exposed thermal pad, designed for efficient space-constrained applications.

Feature Summary

• Integrates dual synchronous buck converters and dual LDO regulators for comprehensive power distribution
• Supports high-frequency operation up to 3MHz to minimize external component size
• Features a compact 16-pin TQFN package with exposed pad for enhanced thermal performance

Applications

• Portable consumer electronics requiring multi-rail power supplies
• Mobile communication devices with strict space constraints
• Embedded systems needing combined switching and linear regulation

Procurement Notes

Verify the specific suffix 'NLZ' against official Renesas documentation to confirm exact pinout and electrical tolerances. Confirm current manufacturing status as product lines may be discontinued or superseded. Ensure compatibility with existing PCB footprints and thermal design requirements before finalizing procurement plans.

Selection Notes

Select this component when a single IC solution is required to generate multiple voltage rails from a single input source. Consider the 3MHz switching frequency for applications prioritizing small passive component sizes over ultra-low noise. Evaluate thermal dissipation capabilities through the exposed pad if operating near maximum load conditions.

Part Context

This part belongs to the ISL9307 family of quad-output PMICs from Renesas. These devices are engineered to replace discrete regulator solutions in portable designs. The family typically offers flexibility in output configuration while maintaining high efficiency across varying load conditions.

Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify that any substitute maintains identical pinout compatibility and regulatory compliance standards.
