ISL97636AIRZ-TK

Overview

The ISL97636AIRZ-TK is a discontinued LED lighting driver IC manufactured by Renesas Electronics Corporation. It features six output channels designed for backlight applications, utilizing a boost DC-DC converter topology with PWM dimming capability. The device operates within a supply voltage range of 6V to 24V and delivers up to 35mA per channel. It is housed in a 24-VFQFN package with an exposed pad, measuring 4x4 mm, and supports surface mount installation. The component functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a boost DC-DC converter for efficient LED power regulation
• Provides independent control over six distinct output channels
• Supports precise brightness adjustment through PWM dimming signals

Applications

• Backlight systems for display panels
• LED lighting driver circuits
• Electronic display modules requiring multi-channel regulation

Procurement Notes

This specific part number is officially listed as obsolete and no longer in production by the manufacturer. Availability is strictly limited to existing stock or surplus inventory from third-party distributors. Verification of authenticity and storage history is critical due to the end-of-life status. Buyers should confirm the exact condition and lot date codes before acquisition, as new manufacturing units are not available directly from Renesas.

Selection Notes

Engineers selecting this component must account for its discontinued status when designing new products. The fixed six-channel configuration and boost topology define its functional scope. Alternative solutions should be evaluated if long-term supply stability is required. Designers should verify that the 24-QFN package dimensions and pinout match their PCB layout constraints, as re-spinning boards for obsolete parts is not feasible.

Part Context

The ISL97636 series belongs to Renesas' portfolio of dedicated LED driver integrated circuits. These components are engineered to simplify the design of complex lighting systems by integrating power switching and control logic into a single compact package. The AIRZ suffix typically denotes automotive-grade qualification or specific environmental testing standards within the Intersil/Renesas naming convention.

Replacement Considerations

Public records indicate ISL97678IRZ-T as a similar replacement option offered by Renesas Electronics Corporation.
