1/1000 dimming support, no flicker occurrence!

DALI (Digital Addressable Lighting Interface) dimming relies on standardized digital communication technology, focusing on the comprehensive advantages of real-time communication execution response, dimming accuracy, and control reliability, and is used in many homes, hotels, and large public transportation systems. It is widely of interest in intelligent lighting systems and has been adopted by many lighting designers. The BP1389 employs a hybrid dimming technology of digital and analog, ensuring not only soft dimming performance but also that the light is reliably dimmed, particularly meeting the dimming accuracy requirements at 1/1000 depth dimming. In conjunction with Lingou's cost-effective ARM0 core 32-bit MCU 033 series, it accurately executes DALI commands to control output current, demonstrating an exponential dimming curve tailored to the human eye, making the dimming process soft and flicker-free.

basic information

BP1389 is applied in CCM dimming operation mode, supports LED multi-channel common anode structure, meets the requirements for DALI dimming for fast startup and dimming response across the entire dimming range, and provides a very small low-frequency ripple current output of less than 1%. With a wide output voltage range of 6 to 42V, a load regulation rate performance of less than ±5% is achieved, ensuring consistency of light output under dimming with multiple lamps combined. * DALI compliant * Push Dimming compatible * Dimming depth 0.1% * Across all voltage ranges PF>0.95, THD<15% * Output current low-frequency ripple <±1% * Output voltage 6-42V
