ISL97672AIRZ-T

Overview

The ISL97672AIRZ-T is a six-channel LED driver IC from the Renesas ISL97672A series, designed for LED lighting applications. It features an integrated boost DC-DC converter and supports PWM dimming control. The device operates within a supply voltage range of 5V to 26.5V and delivers output currents up to 50mA per channel. It is housed in a 20-pin QFN package with an exposed pad (QFN-EP-20) and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

Integrates a six-channel LED driver with an internal boost DC-DC converter topology.
Supports precise brightness regulation through dedicated PWM dimming input control.
Features ultra-low dimming capability for high contrast ratio performance in backlighting.

Applications

LCD TV backlighting systems
Monitor display backlighting
General LED lighting fixtures

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm that the specific suffix 'AIRZ-T' matches the required industrial temperature grade (-40°C to +85°C) and tape-and-reel packaging format. Check current lifecycle status as discontinuation notices may affect long-term availability.

Selection Notes

Select this component when designing circuits requiring independent control of six LED strings with integrated power conversion. Ensure the application demands a boost topology suitable for driving series-connected LED loads. Verify that the 20-QFN footprint aligns with the PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the ISL97672A family of multi-channel LED drivers. It shares functional similarities with related models like the ISL97671AIRZ-T but differs in specific electrical parameters and feature sets. The series is engineered for high-efficiency backlighting solutions in consumer electronics and displays.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate cross-reference options only after verifying pinout compatibility and electrical parameter equivalence with official Renesas engineering support.
