High Efficiency Tunable White LED DC-DC Driver with Bluetooth Smart Connectivity Reference Design
Description
This reference design is a tested DC/DC LED driver designed for tunable white LED luminaires. It is built on a wireless SoC platform which can enable intensity adjustment (dimming) and co-related color temperature (CCT) control using any BLE smart device. Tunable white-light luminaires simulate daylight conditions. With a separate warm-white and cold-white LED string: it allows CCT tuning and helps achieve proper circadian stimulation. TIDA-01096 provides high efficiency DC/DC conversion and allows dimming and color temperature control over more than 1:50 and 1:500 range using analog and PWM methods.
Features
- 98% efficiency over 100% to 50% brightness with analog dimming; 1:50 contrast ratio with analog dimming and 1:500 with PWM dimmingPWM-based dimming with modulation frequency support up to 5 kHzTwo 600-kHz constant current buck drivers with features to synchronize switching frequenciesAmbient light sensor OPT3001-based light measurement enabling daylight harvesting and constant lumen implementations in softwareOvercurrent and over-temperature protection for driver and LED module
