ISL78100ARZ

Overview

The ISL78100ARZ is a high-power LED driver IC from the Renesas ISL78100 series, designed for automotive-grade applications. It integrates a buck-boost topology capable of driving single-channel loads with an output current of 1 A. The device operates within an input voltage range of 2.7 V to 16 V and supports a switching frequency of 1 MHz. Housed in a 20-lead QFN package (4x4 mm), it functions across an extended temperature range of -40°C to +105°C.

Feature Summary

• Integrates buck and boost converter topologies for flexible high-power LED drive configurations.
• Includes built-in PWM dimming capability for precise light control.
• Provides hardware protection against short circuits and thermal overload conditions.

Applications

• High power LED lighting systems
• Automotive exterior lighting modules

Procurement Notes

Verify component authenticity through authorized channels as this part may be discontinued or subject to supply constraints. Confirm RoHS compliance status via official datasheets before integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Validate package dimensions against PCB footprint requirements prior to procurement.

Selection Notes

Select this component when designing single-channel high-power LED drivers requiring buck-boost flexibility. It is suitable for applications needing integrated protection features and PWM dimming. Consider the 20-lead QFN package for space-constrained designs. Verify that the 1 A output current meets specific load requirements.

Part Context

Part of the ISL78100 family of high-power LED drivers by Renesas/Intersil. Designed for robust performance in demanding environments. The ARZ suffix indicates a specific tape and reel or tube packaging variant depending on distribution channel specifications.

Replacement Considerations

Check for direct substitutes within the ISL78100 series such as ISL78100ARZ-T7A. Verify pin compatibility and electrical parameters before substitution.
