ISL9305IRTHBCNLZ-T

Overview

The ISL9305IRTHBCNLZ-T is a quad-output power management IC from Renesas Electronics, integrating two 3MHz buck converters and two low-dropout linear regulators. It operates within a supply voltage range of 1.5V to 5.5V. Output specifications include 1.5V at 800mA, 2.5V at 800mA, and 3.3V at 350mA. The device utilizes a 16-TQFN (4x4) package with an exposed pad for thermal dissipation. It supports I2C-compatible interface control and functions across a temperature range of -40°C to 85°C.

Feature Summary

• Integrates dual high-frequency step-down converters and dual low-input LDOs in a single compact package
• Features I2C-compatible interface for programmable configuration and monitoring
• Supports wide input voltage operation suitable for battery-powered applications

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Battery-operated systems needing efficient power conversion
• Embedded applications with space-constrained PCB layouts

Procurement Notes

Verify component authenticity through authorized channels as the part may be subject to obsolescence notices. Confirm RoHS compliance status and specific suffix variations against official Renesas documentation prior to procurement. Ensure handling procedures account for moisture sensitivity level 3 requirements during storage and assembly processes.

Selection Notes

Select this component when a compact solution combining switching and linear regulation is required. The integrated design reduces external component count compared to discrete solutions. Consider the 3MHz switching frequency for smaller passive components. Verify that the available output currents meet system load requirements without exceeding thermal limits in the target enclosure.

Part Context

This PMIC belongs to the ISL9305 family, designed for portable electronics. It replaces older multi-chip power solutions by consolidating buck and LDO functions. The device addresses the need for high efficiency and small footprint in modern mobile and IoT hardware designs.

Replacement Considerations

Check for direct pin-to-pin replacements such as ISL9305IRTBFNCZ-T or ISL9305IRTBCNLZ-T. Verify functional equivalence regarding output configurations and control interfaces before substitution.
