Overview
iW3605 AC/DC Digital Power Controller for Bleederless Single-Stage High Power Factor Dimmable LED Drivers 1.
0 Features 2.
0 Description ●● Isolated/non-isolated offline120VAC/230VAC LED driver up to 25W 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 ●● No bleeder needed with output power down to 5W for 120VAC/230VAC ●● 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 the use of a small transformer ●● Primary-side sensing eliminates the need for opto-isolator feedback ●● Tight LED current regulation (± 5%) ●● Fast start-up (< 0.
5s without dimmer) ●● Compatible with N...
