ISL9305IRTBCNLZ-T

Overview

The ISL9305IRTBCNLZ-T is a quad-output power management IC (PMIC) manufactured by Renesas Electronics Corporation. It integrates two switching buck converters and two low-dropout linear regulators (LDOs). The device operates with an input voltage range of 1.5V to 5.5V and features a switching frequency of 3MHz. Output 1 provides 1.5V at 800mA, Output 2 provides 2.5V at 800mA, and Output 3 provides 3.3V at 350mA. It is housed in a 16-TQFN (4x4) package with exposed pad and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Integrates dual synchronous buck converters and dual LDOs for efficient multi-rail power generation
• Features high-frequency 3MHz switching operation to minimize external component size
• Includes comprehensive thermal protection and current limiting for system reliability

Applications

• Portable consumer electronics requiring compact power solutions
• Embedded systems with mixed analog and digital power requirements
• Battery-powered devices needing efficient voltage regulation

Procurement Notes

Verify the specific suffix 'NCZ' against official Renesas documentation to confirm exact binning or revision status. Confirm RoHS3 compliance and MSL level 3 handling requirements during storage and assembly. Check for End-of-Life (EOL) notices as availability may be limited.

Selection Notes

Select this PMIC when space-constrained designs require four regulated outputs from a single component. Ensure input voltage stays within 1.5V-5.5V. Verify that the combined load currents do not exceed individual channel limits or thermal dissipation capabilities of the 16-TQFN package.

Part Context

This component belongs to the ISL9305 family of quad-output PMICs designed for portable applications. It consolidates multiple discrete regulator functions into a single integrated circuit, reducing board area and simplifying power distribution network design for complex embedded systems.

Replacement Considerations

Check Renesas datasheets for direct pin-to-pin compatible alternatives within the same product family. Verify if newer revisions have superseded this specific suffix version.
