ISL97635IRZ-T

Overview

The ISL97635IRZ-T is a digitally controlled LED driver IC designed for LCD backlight applications. It features an integrated DC-DC boost converter capable of driving up to eight independent LED channels with regulated current output of 35mA per channel. The device supports PWM dimming and operates within a supply voltage range of 6V to 24V, delivering a maximum output voltage of 34.5V. Operating frequencies are selectable at 600kHz or 1.2MHz. The component is housed in a 24-QFN (4x4mm) package with an exposed pad and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

Digitally controlled regulation of multiple LED channels via SMBus interface
Integrated high-efficiency step-up DC-DC converter topology
Supports precise pulse-width modulation dimming control

Applications

LCD display backlighting systems
Portable electronic device illumination
Monitor and television backlight drivers

Procurement Notes

Verify component authenticity through authorized Renesas distributors due to end-of-life status. Confirm RoHS3 compliance and moisture sensitivity level 3 handling requirements during storage and assembly. Review product change notices for any packaging or material revisions prior to final design implementation.

Selection Notes

Select this component when designing multi-channel LED backlight solutions requiring digital control and integrated power conversion. Ensure input voltage ranges match the 6V to 24V specification and verify thermal management capabilities for the QFN package. Consider the discontinued status for long-term production planning.

Part Context

This part belongs to the ISL97635 family of LED drivers from Renesas Electronics. It serves as a specialized power management solution for visual display technologies, replacing older discrete driver designs with an integrated approach that reduces board space and simplifies system architecture for modern LCD panels.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, alternative components must be evaluated based on functional equivalence and pin compatibility by the design engineer.
