ISL9307IRTAANGZ-T

Overview

The ISL9307IRTAANGZ-T is a mini-PMIC designed for low-voltage microprocessors and battery-powered applications. It integrates two high-efficiency synchronous buck converters and two low-dropout (LDO) regulators within a single package. The device supports an input voltage range of 1.5V to 5.5V, making it suitable for single lithium-ion or polymer cell systems. It features adjustable output voltages for the buck converters and fixed outputs for the LDOs, providing a compact power solution for portable electronics.

Feature Summary

• Integrates dual synchronous step-down converters and dual LDO regulators in a single IC
• Supports wide input voltage range compatible with single-cell lithium batteries
• Provides flexible output voltage adjustment for primary power rails

Applications

• Powering low-voltage microprocessors
• Single lithium-ion or lithium-polymer battery powered devices
• Portable consumer electronics requiring multiple voltage rails

Procurement Notes

Verify current availability status as this component may be obsolete or subject to limited supply conditions. Confirm exact ordering suffixes match required pin configurations and packaging options. Cross-reference datasheet revisions to ensure compatibility with existing designs. Check for manufacturer-end-of-life notices before finalizing procurement plans.

Selection Notes

Select this component when space-constrained designs require integrated buck and LDO regulation from a single source. Ensure input voltage requirements align with the 1.5V to 5.5V operational range. Verify that the integrated current capabilities meet the load demands of the target microprocessor and peripheral circuits without external amplification.

Part Context

This part belongs to the ISL9307 family of mini-PMICs from Renesas Electronics. These devices are engineered to simplify power management in mobile and handheld applications by reducing component count and board area compared to discrete solutions.

Replacement Considerations

Check for parametric equivalents such as ISL9307IRTAAJBZ-T7A or ISL9307IRTAAJLZ-T7A if available. Verify functional compatibility and pin-out alignment before substitution.
