Overview
The ISL97672BIRZ-T is a six-channel LED driver IC featuring an integrated boost DC-DC converter and ultra-low dimming capability. It operates within a supply voltage range of 4.5V to 26.5V, delivering up to 50mA per channel with a maximum output voltage of 45V. The device supports PWM dimming at frequencies between 200kHz and 1.5MHz. Packaged in a 20-VFQFN (3x4) exposed pad format, it functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates a high-efficiency boost DC-DC converter for driving multiple LED strings from lower input voltages.
- Provides independent current regulation for six output channels to ensure uniform brightness control.
- Supports high-frequency PWM dimming signals for flicker-free operation in display backlight applications.
Applications
- LCD panel backlighting systems
- Mobile device display drivers
- Portable electronic equipment lighting
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status as the component may be subject to End-of-Life notices. Ensure the 20-QFN package dimensions match the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring six independently controlled LED channels driven by a single boost regulator. It is suitable for applications needing precise current matching across outputs and support for high-frequency PWM dimming signals without external switching components.
Part Context
This part belongs to the ISL97672 family of LED drivers designed for portable electronics. It shares architectural similarities with other models in the series but is distinguished by its specific six-channel configuration and ultra-low dimming performance characteristics tailored for modern display technologies.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing boost inductors and capacitors if considering alternative drivers from the same manufacturer family.
