ISL9307IRTAAJBZ-T7A

Overview

The ISL9307IRTAAJBZ-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. Output channels one and two provide adjustable voltages from 0.8V to 5.5V with a maximum current capacity of 1.5A each. Output channel three delivers a fixed 2.8V at 300mA. The component utilizes a 16-WQFN package with an exposed pad, supporting surface-mount installation.

Feature Summary

• Integrates dual synchronous buck converters and dual LDOs for compact multi-rail power solutions
• Supports wide input voltage range suitable for various battery and system power sources
• Features high-current capability on primary output channels for demanding loads

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Embedded systems with mixed analog and digital power requirements
• Industrial control modules needing stable low-noise power supplies

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct output specifications and pinout compatibility. Confirm end-of-life status and availability of equivalent replacement parts before finalizing design implementations. Cross-reference manufacturer documentation for updated assembly and labeling notices.

Selection Notes

Evaluate thermal performance requirements based on the total power dissipation of all four outputs within the 16-WQFN package. Ensure input voltage levels remain within the specified operational range for reliable regulation. Consider the combined current demands of the load circuits to verify that the 1.5A and 300mA limits are not exceeded under peak operating conditions.

Part Context

This component belongs to the ISL9307 family of quad-output PMICs designed for space-constrained applications. It consolidates multiple power stages into a single footprint, reducing board area compared to discrete solutions. The integration supports efficient power distribution in systems requiring both high-current switching and low-noise linear regulation.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include ISL9307IRTAAJFZ-T7A and ISL9307IRTAAJLZ-T7A. Verify functional equivalence and package compatibility when transitioning between these variants.
