ISL97684IRTZ-T

Overview

The ISL97684IRTZ-T is a four-channel LED driver IC featuring an integrated boost DC-DC converter. It supports PWM dimming with a maximum output current of 50mA per channel and operates within a supply voltage range of 4V to 26.5V. The device utilizes a 16-TQFN (3x3) package, offers a switching frequency of 600kHz, and functions across a temperature range of -40°C to 85°C.

Feature Summary

• Integrates a boost topology DC-DC converter for efficient LED powering
• Provides independent control for four distinct LED channels
• Supports high-resolution pulse-width modulation dimming

Applications

• LED backlighting systems
• Portable electronic displays
• Mobile device illumination

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity handling requirements prior to assembly. Review official discontinuation notices for final purchase deadlines and last-time buy information.

Selection Notes

Evaluate the 50mA per-channel current limit against target LED forward current requirements. Ensure the input supply voltage remains within the specified 4V to 26.5V operational window. Consider thermal dissipation capabilities inherent to the small 16-TQFN footprint during continuous operation.

Part Context

This component belongs to the Renesas ISL97684 series, designed specifically for multi-channel LED regulation. It replaces earlier discrete solutions by integrating power switches and control logic into a compact surface-mount package suitable for space-constrained consumer electronics.
