The XP2115/6 is a digital high-performance DC/DC buck lighting control IC designed for mid-to-high-end dimmable solid-state lighting (SSL) driver applications.The XP2115/6's digital dimming control enables high-precision DC dimming from 0.1% to 100% and ensures a soft, smooth, and step-free dimming process for highly optimised illumination quality and user experience.
01 Product Features
Low-side Buck topology, power range 5W-150W.
■ Input voltage range 20-80V, output voltage range 5V to 95% of the input voltage.
■ Full high-precision DC dimming (equipped with a certain output capacitance), ripple and PWM dimming signal frequency-independent
■ 0.1% dimming depth, 0.002% dimming resolution, dimming process CNC softening processing
■ Full dimming curve (including the lowest dimming point) with excellent voltage / load adjustment rate
Two independent dimming interfaces
-Field configurable level or PWM dimming
-Field configurable PWM dimming duty cycle remapping, to solve the optocoupler in the low duty cycle signal distortion
-Configurable "phase or" relationship between the two dimming signals to meet the requirements of IOT applications.
■ XP2116 is equipped with UART communication interface, which can realise LED dimming as well as parameter configuration and fault information feedback function.
