ISL9307IRTAANGZ-T7A

Overview

The ISL9307IRTAANGZ-T7A is a mini-PMIC featuring four independent regulators: two synchronous buck converters and two low-input linear regulators. It operates with an input voltage range of 1.5V to 5.5V. The switching frequency is fixed at 3MHz. Output 1 and 2 provide up to 1.5A each with adjustable voltages from 0.8V to 5.5V. Outputs 3 and 4 are LDOs fixed at 2.8V with 300mA capability. It is housed in a 16-TQFN (4x4) package.

Feature Summary

• Integrates dual synchronous step-down converters and dual low-input LDOs into a single compact IC.
• Supports wide input voltage ranges suitable for battery-powered portable devices.
• Utilizes a high 3MHz switching frequency to minimize external component size.

Applications

• Powering low-voltage digital logic and memory in handheld devices
• System power management for mobile communication equipment
• Portable consumer electronics requiring multiple regulated rails

Procurement Notes

Verify the obsolete status of this specific part number before design finalization. Confirm that alternative Renesas PMICs meet all electrical requirements. Check for updated packaging or labeling notices issued by the manufacturer. Ensure supply chain stability for replacement components during production lifecycle.

Selection Notes

Select this component when space constraints require integrating multiple regulator types. It is suitable for applications needing both high-current switching outputs and precise low-noise LDO supplies. Verify that the 3MHz frequency aligns with EMI requirements and inductor availability.

Part Context

This device belongs to the ISL9307 family of integrated mini-Power Management ICs designed for portable applications. It consolidates functions typically requiring separate discrete components, reducing board area and simplifying power distribution networks for complex system architectures.

Replacement Considerations

Public confirmed substitute part numbers include ISL9307IRTAAJBZ-T7A and ISL9307IRTAAJLZ-T7A. These variants offer parameter equivalence but may differ in suffix specifications or manufacturing origin. Validate pin compatibility and thermal performance before substitution.
