Various LED Ring Lighting Patterns Reference Design
Texas Instruments
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.
Features
- Vivid lighting patterns with 12-Bit: 29-kHz PWM dimming through an I2C interfaceUltra-Low standby current down to 10 μA with automatic power saving modeProgrammable banks (R/G/B) for easy software control of each colorDynamically adjusts brightness on ambient light sense
