ISL9307IRTAAJFZ-T7A

Overview

The ISL9307IRTAAJFZ-T7A is a quad-output power management IC featuring two synchronous buck converters and two low-dropout regulators. It operates within an input voltage range of 1.5 V to 5.5 V, delivering up to 1.5 A on the adjustable buck outputs and 300 mA on the fixed LDO output. The device integrates a 3 MHz switching frequency for compact passive design. Packaged in a 16-pin TQFN with an exposed pad, it supports surface-mount assembly and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates dual synchronous buck and dual linear regulator topologies for comprehensive power sequencing.
• Supports high-frequency operation at 3 MHz to minimize external component footprint.
• Provides flexible output configurations with adjustable buck rails and fixed LDO supplies.

Applications

• Portable consumer electronics requiring multi-rail power distribution
• Embedded systems utilizing mixed-signal processing architectures
• Industrial control modules needing stable voltage regulation

Procurement Notes

Verify current availability status as this component may be discontinued or subject to end-of-life notices. Confirm that the specific suffix matches required pinout and thermal characteristics. Ensure compatibility with existing PCB layouts before finalizing orders due to potential supply chain constraints.

Selection Notes

Select this component when designing systems requiring four distinct regulated voltages from a single IC. It is suitable for applications prioritizing board space efficiency over discrete solutions. Consider the 1.5 A current limit for primary loads and verify thermal dissipation requirements for the TQFN package under maximum load conditions.
