CR5608
AC/DC Digital Power Controller for Single-Stage High Power Factor Dimmable LED Drivers
1.0 Features
●● Isolated/non-isolated offline120VAC/230VAC LED driver up to 15W output power
●● Wide line frequency range (from 45Hz to 66Hz)
●● Meets IEC61000-3-2 current harmonic requirement
●● Total harmonic distortion < 20% with PF > 0.92
●● Wide dimmer compatibility xx Leading-edge dimmer xx Trailing-edge dimmer
●● Dimming range from 10% to 100%
●● Resonant control to achieve high efficiency (typical > 82% without dimmer)
●● Over-temperature LED current foldback
●● Small solution size xx Single-stage topology reduces part counts xx 90kHz maximum switching frequency enables small transformer use
●● Primary-side sensing eliminates the need for opto-isolator feedback
●● Tight LED current regulation (± 5%)
●● Fast start-up (< 0.5s without dimmer)
●● Compatible with NEMA SSL6 dimming curve standard
●● Multiple protection features that i...
