ISL6534CV-TR5229

Overview

The ISL6534CV-TR5229 is a Power Management IC (PMIC) from Renesas Electronics Corporation, designed for multi-voltage power supply applications. It integrates three output channels: two synchronous step-down (buck) converters and one low-dropout (LDO) linear regulator. The switching regulators operate at a frequency range of 300kHz to 1MHz. This component combines PWM control with linear regulation in a single package, offering a compact solution for systems requiring multiple regulated voltage rails.

Feature Summary

• Integrates dual synchronous buck converters and a single LDO regulator within one IC
• Supports adjustable switching frequencies between 300kHz and 1MHz
• Provides a compact multi-rail power solution combining switching and linear technologies

Applications

• Systems requiring multiple distinct voltage rails from a single power source
• Embedded electronics needing combined high-efficiency switching and low-noise linear regulation
• Portable devices where space-constrained power management is critical

Procurement Notes

Verify the specific suffix TR5229 against official Renesas documentation to confirm tape and reel specifications. Confirm RoHS compliance status as sources vary. Check lifecycle status, as some listings indicate obsolete status. Ensure the supplier provides valid traceability for this discontinued or legacy part number.

Selection Notes

Select this component when a design requires two synchronous buck outputs and one LDO output in a single footprint. Consider the 300kHz-1MHz frequency range for EMI and inductor size trade-offs. Verify that the thermal performance of the 24-pin PTSSOP package meets the system's heat dissipation requirements for the combined load currents.

Part Context

This part belongs to the Renesas Intersil PMIC family, specifically designed for integrated power solutions. It merges the efficiency of synchronous rectification with the simplicity of linear regulation. The device is intended for applications where board space is limited and multiple voltage levels are necessary for digital logic and analog circuits.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Due to potential obsolete status, verify compatibility with alternative Renesas PMICs that offer similar dual-buck and single-LDO configurations.
