ISL6402IR-T

Overview

The ISL6402IR-T is a Power Management Integrated Circuit (PMIC) from Intersil, designed for high-performance applications that require multiple voltage outputs. It integrates dual synchronous buck converters and one low-dropout (LDO) regulator within a single package. The device operates with an input voltage range of 0.8V to 24V and supports a switching frequency of 340kHz. It is housed in a 28-pin QFN EP package.

Feature Summary

• Integrates dual synchronous step-down converters and a linear regulator
• Supports wide input voltage range up to 24V
• Operates at a fixed switching frequency of 340kHz
• Designed for compact PCB layouts using a low-profile package

Applications

• Portable electronics requiring multiple power rails
• Industrial control systems
• Communication equipment

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the supplier provides original Intersil or Renesas branding to avoid counterfeit components. Check for End-of-Life notifications if long-term supply stability is required.

Selection Notes

Select this component when a combined solution for DC-DC conversion and LDO regulation is needed to save board space. Consider the 340kHz switching frequency for balancing efficiency and component size. Verify that the load requirements for the dual buck and single LDO channels fit within the IC's current capabilities.

Part Context

This part belongs to the Intersil PMIC family, which consolidates multiple power stages into single packages. It replaces discrete solutions involving separate controllers and regulators, reducing bill of materials count. The integration helps minimize electromagnetic interference and simplifies thermal management in dense designs.

Replacement Considerations

Check for direct pin-to-pin replacements within the ISL6402 series. Verify compatibility with existing PCB footprints and thermal pads. Ensure substitute parts support the same 28-pin QFN EP package and electrical specifications.
