ISL97636IRZ

Overview

The ISL97636IRZ is a discontinued LED lighting driver IC manufactured by Renesas Electronics Corporation. It features six independent output channels designed for regulated PWM dimming applications. The device operates as a DC-DC boost converter with an internal switch, supporting a supply voltage range from 6V to 24V and delivering up to 35mA per channel. It functions at a switching frequency of 1.2MHz and provides a maximum output voltage of 34.5V. The component is housed in a 24-VFQFN package with an exposed pad and is rated for operation between -40°C and +85°C.

Feature Summary

Six-channel LED driver architecture with individual current regulation
Integrated boost topology with internal power switch
Supports PWM dimming control for backlight applications

Applications

LED backlight systems
General LED lighting drivers

Procurement Notes

Verify component status carefully as the ISL97636IRZ is officially obsolete and no longer manufactured. Confirm availability through secondary market distributors or check for valid replacement part numbers such as the ISL97678IRZ-T before initiating procurement processes. Ensure all handling procedures account for moisture sensitivity level 3 requirements during storage and assembly.

Selection Notes

Select this component only for legacy designs requiring a six-channel boost LED driver with 35mA output capability. Consider the discontinuation status when planning long-term production runs. Evaluate thermal performance within the specified operating temperature range and ensure the 24-QFN package fits the target PCB layout constraints.

Part Context

This part belongs to the ISL97636A series of LED drivers from Renesas. It is functionally related to other models like the ISL97673, which offers similar six-channel capabilities but with different current ratings and automotive qualification levels. The series targets efficient backlighting solutions using integrated boost converters.
