XDP™ Digital Power
Data Sheet
Revision 1.1 Features
•
•
• UART interface to control driver output and reading operating status
Flicker-free output dimming by analog reduction of driving current down to 1%
Integrated two stage digital controller allows a reduced number of external parts, optimizes Bill of
Materials (BOM) and form factor.
•
Two-stage design eliminates AC ripple on output.
•
Supports universal AC and DC input voltage (90 V rms to 305 V rms) nominal.
•
High efficiency up to 90%
•
Multi-control output (Constant Current (CC)/Constant Voltage (CV)/Limited Power (LP)
•
Performance and protection related driver parameters are configurable via UART interface allowing for
design flexibility and optimization.
•
Low harmonic distortion (Total Harmonic Distortion (THD) < 15%) down to 30% nominal load …
