ISL97636AIRZ-T

Overview

The ISL97636AIRZ-T is a six-channel LED driver IC manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 6V to 24V and delivers a regulated output current of 35mA per channel. The device utilizes an internal boost DC-DC converter topology with a switching frequency of 1.2MHz. It supports PWM dimming control and features an integrated power switch. The component is housed in a 24-VFQFN exposed pad package, measuring 4x4 mm, and is designed for surface mount installation. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Six independent output channels for driving LED arrays
• Integrated boost regulator with internal power switch
• Supports pulse-width modulation dimming control
• Regulated constant current output capability

Applications

• LED backlighting systems
• General LED lighting applications

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level prior to assembly. Check for product change notifications regarding packaging or material revisions. Ensure storage conditions meet humidity requirements to prevent damage before soldering.

Selection Notes

Select this component for designs requiring multiple LED channels with integrated boost regulation. Consider the 24-QFN package size for space-constrained layouts. Evaluate thermal performance given the exposed pad requirement. Verify input voltage compatibility with the 6V to 24V operational range.
