Overview
The ISL97635IRZS2038 is an LED driver IC manufactured by Renesas Electronics Corporation, belonging to the ISL97635 series. It functions as a DC-DC boost converter with six independent output channels, each capable of delivering up to 35mA. The device supports PWM dimming and operates at switching frequencies of 600kHz or 1.2MHz. It accepts a supply voltage range from 6V to 24V and can drive loads up to 34.5V. Packaged in a 24-QFN (4x4mm) surface-mount format with an exposed pad, it is designed for backlight applications within an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates a high-efficiency boost DC-DC converter topology with internal power switches for compact system design.
- Provides six individually controllable current-regulated outputs suitable for multi-zone LED backlighting.
- Supports digital control interfaces for precise brightness regulation and operational monitoring.
Applications
- LCD panel backlighting for monitors
- Television display systems
- Industrial LCD modules
Procurement Notes
Verify component authenticity through authorized distributors due to end-of-life status. Confirm package marking and date codes against official datasheets. Check for RoHS compliance documentation. Validate pinout compatibility during replacement planning. Request batch-specific test reports if available.
Selection Notes
Select this component for designs requiring six-channel LED current regulation with integrated boost conversion. Ensure input voltage ranges between 6V and 24V match system requirements. Verify thermal management capabilities for the QFN package under maximum load conditions. Consider EMI filtering needs for 600kHz/1.2MHz operation.
Part Context
This part belongs to the ISL97635 family of LED drivers from Renesas. It shares architectural similarities with other members like the ISL97635AIRZ-T but differs in specific suffix designations. The series targets cost-sensitive, space-constrained display applications requiring reliable multi-channel current control.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Renesas technical support for qualified alternatives given the product's discontinued status.
