ISL97672AIRZ-TK

Overview

The ISL97672AIRZ-TK is a six-channel LED driver IC from the Renesas ISL97672A series, designed for backlight applications. It features an integrated boost DC-DC converter with internal switches and supports PWM dimming control. The device operates within a supply voltage range of 4.5V to 26.5V and delivers up to 50mA per channel at a maximum output voltage of 45V. Operating frequencies range from 200kHz to 1.5MHz. It functions reliably across a temperature range of -40°C to +85°C and is housed in a 20-QFN (3x4) package.

Feature Summary

Integrates a boost DC-DC converter with internal power switches for efficient LED driving
Provides independent current regulation for six output channels
Supports high-resolution PWM dimming for brightness control

Applications

LCD backlight systems
LED lighting modules

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notices, as this specific part number may have limited availability. Ensure the ordering suffix matches the required tape-and-reel packaging configuration for automated assembly processes.

Selection Notes

Select this component when designing circuits requiring multi-channel LED regulation with integrated power conversion. It is suitable for applications needing precise PWM dimming capabilities and compact board space due to its QFN footprint. Verify that the input voltage and load requirements align with the specified 4.5V to 26.5V operating range and 50mA channel current limit.

Part Context

This part belongs to the ISL97672 family of LED drivers, which are optimized for backlighting solutions. The 'AIRZ' designation indicates automotive-grade qualification and lead-free RoHS-compliant packaging, while the '-TK' suffix specifies the tape-and-reel shipping format. It shares core functionality with other variants in the series but differs in packaging and specific qualification standards.

Replacement Considerations

Consult official cross-reference lists for verified substitutes such as the ISL97672BIRZ or ISL97673IRZ. Ensure any replacement maintains compatibility with the 20-QFN package and meets the same electrical specifications for voltage, current, and thermal performance.
