ISL6413IR

Overview

The ISL6413IR is a triple-output power management integrated circuit manufactured by Intersil, now part of Renesas. It integrates a single synchronous buck converter and two low-dropout (LDO) regulators to provide efficient voltage regulation for complex systems. The device features a wide input supply voltage range of 3V to 3.6V. Output capabilities include one high-current buck output and two lower-current LDO outputs, with specified current ratings of 200mA, 300mA, and 400mA depending on the specific regulator stage. It operates within an industrial temperature range of -40°C to +85°C and is housed in a compact QFN-24 (4x4mm) package.

Feature Summary

• Integrates a single synchronous buck converter alongside dual low-dropout linear regulators for combined switching and linear efficiency.
• Provides three independent regulated output rails from a single narrow input voltage window.
• Designed for space-constrained applications utilizing a small footprint QFN package.

Applications

• Portable electronic devices requiring multiple voltage rails
• Embedded systems with mixed analog and digital power needs
• Industrial control modules operating in extended temperature ranges

Procurement Notes

Verify the manufacturer designation as Intersil or Renesas, as corporate acquisitions may affect labeling. Confirm the exact suffix (e.g., IR vs. IRZ) to ensure correct RoHS compliance status and lead-free specifications. Check the package marking code against the QFN-24 physical dimensions to prevent assembly errors. Ensure the supplier provides valid traceability documentation for automotive or industrial grade components if required by your system specifications.

Selection Notes

Select this component when a design requires three distinct voltage levels derived from a narrow 3V–3.6V source. The integration of a synchronous buck with LDOs reduces external component count compared to discrete solutions. Consider the thermal dissipation requirements of the QFN-24 package under maximum load conditions. Verify that the required output currents align with the specific buck and LDO channels available in this triple-output configuration.

Part Context

This part belongs to the Intersil/Renesas portfolio of power management ICs designed for portable and embedded applications. It represents a consolidation strategy where multiple voltage regulators are merged into a single chip to save board space. Similar parts in this category typically focus on narrow input ranges suitable for battery-powered or single-cell lithium-ion applications.
