1 of 6 1 description the IW3616 is a two-stage, high-performance ac/dc offine power supply controller for dimmable led luminaires. it applies advanced digital control technology to detect the dimmer type and phase, which provides dynamic impedance to interface the dimmer and control the led brightness at the same time. the IW3616 uses dialogs unique digital flickerless tm technology to eliminate visible ficker in the entire dimming range and minimize low frequency output ripple current. with advanced dimmer detection technology, the IW3616 can operate with most wall dimmers including leading-edge dimmers (r-type or r-l type) and trailing-edge dimmers (r-c type). in addition, the IW3616s cycle-by-cycle waveform analysis technology allows fast dimmer setting response. when no dimmer is on the line, the IW3616 optimizes the power factor and minimizes the current harmonic distortion to the ac line. the IW3616 operates the main power converter that delivers constant current to the led load in quasi-resonant mode to provide high power effciency and minimize electro-magnetic interference (emi). it uses dialog s patented primaccurate tm primary-side sensing technology to achieve excellent led current regulation under different ac line and led load voltages, without using a secondary-side feedback circuit and eliminating the need for an optocoupler . the IW3616 minimizes the external components count by simplifying the emi flter with dialog s ez-emi ? technology. the intelligent dimmer detection technology eliminates the need for a high-power bleeder . additionally, the digital control loop of the IW3616 maintains stable overall operating conditions without the need for loop compensation components. 2 features isolated/non-isolated offine 120v ac /230v ac led driver up to 12w output power wide line frequency ranges (from 45hz to 66hz) meets iec61000-3-2 requirement total harmonic distortion < 15% with pf > 0.95 wide dimmer compatibility x leading-edge dimmer x trailing-edge dimmer x digital dimmer x occupancy sensors and timers under 20% output ripple current wide dimming range from 1% to 100% flickerless tm led dimming resonant control to achieve high effciency (typical > 85% without dimmer) over-temperature led current foldback small solution size x two-stage topology enables small-size input and output flter capacitors x 200khz maximum switching frequency enables small transformer 3 applications dimmable led retroft lamps up to 12w dimmable led ballast and luminaires up to 12w x intelligent dimmer interface eliminates dedicated high-power bleeder primaccurate ? primary-side sensing eliminates the need for optocoupler feedback tight led current regulation ( 5%) fast start-up (< 0.5s without dimmer) supports hot-plug led module (zhaga) compatible with nema ssl6 dimming curve standard supports wide led output voltage range multiple protection features: x led open-circuit and short-circuit protection x over-current and over-temperature protection x current sense resistor short-circuit protection x ac line over-voltage/-frequency protection IW3616 ac/dc digital power controller for high power factor dimmable led drivers rev. 1.1 product summary ? 2016 dialog semiconductor www.dialog-semiconductor.com 10-may-2016
