ISL9307IRTAANYZ-T7A

Overview

The ISL9307IRTAANYZ-T7A is a mini-PMIC featuring two synchronous buck converters and two low-input LDOs. It operates with an input voltage range of 1.5V to 5.5V. The buck outputs deliver up to 1.5A each, while the LDOs provide fixed or adjustable voltages. Switching frequency is 3MHz. It supports output voltages from 0.8V to 5.5V for bucks and specific rails for LDOs. Operating temperature spans -40°C to +85°C in a 16-TQFN package.

Feature Summary

• Integrates dual synchronous step-down converters and dual low-input linear regulators
• Designed for powering low-voltage microprocessors from single lithium sources
• Compact integrated power management solution for multiple voltage rails

Applications

• Powering low-voltage microprocessors
• Battery-powered applications using single lithium-ion cells
• Systems requiring multiple regulated voltage rails from one source

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Check datasheet revisions for pinout consistency. Confirm moisture sensitivity level handling during assembly. Validate thermal performance within specified operating temperature range. Ensure compatibility with existing PCB layout constraints.

Selection Notes

Consider the integrated nature of dual bucks and LDOs for space-constrained designs. Evaluate current requirements against the 1.5A buck capability. Assess if the 3MHz switching frequency suits EMI constraints. Verify input voltage compatibility with available battery sources. Review package dimensions for mechanical fit.
