This reference design enables human-machine interface scenarios with an LED ring that utilizes two LP5024 LED drivers to create vivid lighting patterns. Design helps to resolve common challenges for end equipment with complicated lighting patterns and constant voltage supply. This design can also adjust LP5024 brightness with analog dimming without impacting the lighting pattern contrast ratio on dynamic ambient light sense.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
