0 Description ● 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.
The LED brightness is modulated by PWM-dimming.
The iW3602-30C’s unique digital control technology eliminates visible flicker.
The iW3602-30C can operate with all dimmer schemes including leading-edge dimmer and other dimmer configurations such as R-type, or R-L type.
When a dimmer is not present, the controller can automatically detect that there is no dimmer.
The iW3602-30C operates in a quasi-resonant mode to provide high efficiency.
It offers a number of key builtin features and uses advanced primary-side sensing technology to achieve excellent line and load regulation without secondary feedback circuitry.
Additionally, its pulseby-pulse waveform analysis technology allows accurate LED current regulation.
The iW3602-30C maintains stability over all operating conditions without the need for loop compensation components.
Therefore, the device minimizes external component count, simplifies EMI design, and ...
