Description

The TIDA-01096 TI design is a tested DC-DC LED driver sub system 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 thereby helps achieving proper circadian stimulation. TI design 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 dimming
  • PWM based dimming with modulation frequency support up to 5 kHz
  • Two 600 kHz constant current buck drivers with feature to synchronize the switching frequencies
  • Ambient light sensor OPT3001 based light measurement enabling daylight harvesting and constant lumen implementations in software
  • Overcurrent and over temperature protection for driver and LED module
