Overview
The ISL97694AIRTZ-TK is a six-channel LED lighting driver IC manufactured by Renesas Electronics Corporation. It utilizes a boost topology to drive LEDs with an output voltage of 26 V and a maximum channel current of 30 mA. The device operates on a supply voltage range of 2.4 V to 5.5 V and supports a switching frequency between 400 kHz and 1.5 MHz. It features PWM dimming control and includes open LED protection. The component is housed in a 20-QFN package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Six independent output channels for multi-LED configurations
- Integrated boost DC-DC converter for efficient power regulation
- Supports high-resolution PWM dimming control
- Built-in protection against open LED conditions
Applications
- LED backlighting systems
- General LED lighting drivers
- Portable electronic displays
Procurement Notes
Verify the specific suffix 'TK' against official Renesas documentation, as standard listings often reference 'T' or 'TZ'. Confirm end-of-life status via Product Change Notices (PCN). Ensure compatibility with existing PCB footprints for the 20-QFN package. Check moisture sensitivity level requirements for storage and handling procedures prior to assembly.
Selection Notes
Select this component when a six-channel solution with integrated boost conversion is required. Verify that the input voltage range of 2.4 V to 5.5 V aligns with the system power supply. Ensure the 30 mA per channel current rating meets the target LED specifications. Consider the operating temperature range of -40°C to +85°C for environmental suitability.
Part Context
This part belongs to the ISL97694 series of LED drivers from Renesas. It is designed for applications requiring multiple LED channels driven from a single low-voltage source. The series typically includes variants with different packaging options such as tube or tape-and-reel formats. It serves as a specialized power management IC for display and lighting industries.
Replacement Considerations
Check for direct substitutes within the ISL97694 family, such as ISL97694AIRTZ or ISL97694AIRTZ-T. Verify pin-to-pin compatibility if considering alternative manufacturers. Review PCNs for any functional changes in successor components.
