The XP3318 is a digital performance high-voltage DC/DC (Flyback/Buck) lighting controller that provides high precision DC dimming from 0.1% to 100% and ensures a soft, smooth, stepless,
and noiseless dimming process, maximising the quality of the lighting and the user's perception of the lighting.
01 Product Features
● 0.1%-100% depth DC dimming, 1/65536 (16 bit) dimming resolution, stepless fine dimming.
● High-precision primary-side constant current/voltage (+-3%), 8-block primary-side constant power control, suitable for a wide range of mid- to high-end solid-state lighting dimming scenarios.
● Two dimming multiplication, convenient for the maximum current setting requirements of different gears.
● Supports vice-side CC/CV feedback or hybrid feedback, optimising the cost of vice-side feedback control.
● UART digital communication interface, the host computer can carry out digital dimming, real-time detection of LED driver status and parameters.
● Built-in PF-com and XP3323 PFC IC two-way real-time communication, optimising the two-stage cooperation in start-stop, standby and error reporting state.
