Supports PWM dimming control for backlight regulation
Provides eight independent output channels

Applications

Backlight systems

Procurement Notes

Verify component status as the RT8566GCP is listed as obsolete with an end-of-life notification dated September 2025. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints and design requirements before procurement due to discontinuation.

Selection Notes

Select this component for designs requiring eight-channel LED driving with integrated boost conversion. Consider the 28-TSSOP-EP package constraints and thermal management needs. Verify that the input voltage range of 9V to 28V aligns with system power rails. Evaluate alternative components if long-term supply stability is required given the obsolete status.

Part Context

This part belongs to the RT8566 series of LED drivers from Richtek. It is categorized under Power Management ICs (PMIC) specifically for LED driving. The device is distinct from other Richtek models like the RT8560A or RT8510GQW which offer different channel counts and current capabilities.
