ISL9307IRTAANYZ-T

Overview

The ISL9307IRTAANYZ-T is a mini-PMIC integrating two synchronous buck converters and two low-dropout (LDO) regulators. It features four outputs: two adjustable buck channels supporting up to 1.5A each, and two fixed LDO channels providing 2.8V at 300mA. The device operates with an input voltage range of 1.5V to 5.5V and utilizes a 3MHz switching frequency. Packaged in a 16-TQFN (4x4mm) surface-mount case, it supports output voltages from 0.8V to 5.5V for the buck stages.

Feature Summary

Integrates dual high-current synchronous step-down converters and dual low-dropout linear regulators within a single compact package.

Applications

Powering multiple voltage rails for low-voltage microprocessors
Battery-powered systems using single lithium-ion or lithium-polymer cells

Procurement Notes

Verify component status as this part number may be obsolete. Confirm availability through authorized distributors or check for parameter-equivalent substitutes such as ISL9307IRTAAJBZ-T7A. Ensure the specific suffix matches required packaging and temperature ratings before procurement.

Selection Notes

Select this IC for applications requiring a compact power solution for processors powered by single-cell lithium batteries. Consider the 3MHz switching frequency for smaller external inductor sizes. Verify that the 1.5A buck current and 300mA LDO current meet system load requirements.

Part Context

This component belongs to the ISL9307 family of mini-PMICs designed for portable electronics. It consolidates power management functions typically handled by discrete components, reducing board space and simplifying design for battery-operated devices requiring multiple regulated voltage rails.

Replacement Considerations

Check for parameter-equivalent parts like ISL9307IRTAAJBZ-T7A if the primary model is unavailable. Verify pin compatibility and electrical specifications match the original design requirements.
