Overview
Isolated AC/DC offline 100VAC/230VAC LED driver with different external components value Line frequency ranges from 45Hz to 66 Hz Intelligent wall dimmer detection x Leading-edge dimmer x No-dimmer detected x Unsupported dimmer Hybrid dimming scheme Wide dimming range from 1% up to 100% No visible flicker Resonant control to achieve high efficiency, 85% without dimmer Temperature compensated LED current Small size design x Small size input bulk capacitor x Small size output capacitor x Small transformer Primary-side sensing eliminates the need for optoisolator feedback and simplifies design Tight LED current regulation ± 5% Fast start-up, typically 10µA start-up current Hot-plug LED module support The iW3602-30C is a high performance AC/DC offline power supply controller for dimmable LED luminaires, which uses advanced digital control technology to detect the dimmer type and phase. The dimmer conduction phase controls the LED brightness.
