1 of 7 1 description the IW3630 is a two-stage, high-performance ac/dc offine power supply controller for dimmable led luminaires with analog dimming interface. it controls led current based on analog input voltage on the dimming pin. it has a built-in 0-10v dimming interface that works directly with 0-10v dimming systems, eliminating the need for a driver circuit and microcontroller. it also provides a pwm digital interface to support wireless ssl applications, without adding auxiliary power supplies. the IW3630 uses dialogs unique digital flickerless tm technology to eliminate visible ficker in the entire dimming range and to minimize low frequency output ripple current. the IW3630 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 IW3630 minimizes the external components count by simplifying the emi flter with dialog s ez-emi ? technology. additionally, the digital control loop of the IW3630 maintains stability over all operating conditions without the need for loop compensation components. 2 features isolated/non-isolated offine 100v ac /277v ac led driver controller meets iec61000-3-2 requirements total harmonic distortion < 15% with power factor > 0.95 analog input dimming level control built-in 0-10v isolation transformer driver pwm digital interface under 10% output ripple current wide dimming range from 1% to 100% flickerless tm led dimming technology quasi-resonant control to achieve high effciency (typical > 85%) 3 applications dimmable led ballast with analog input for dimming control dimmable led ballast with 0-10v interface for dimming control wireless ssl lighting output power up to 45w small size x two-stage topology enables small-size input and output flter capacitors x 200khz maximum switching frequency enables small transformer primaccurate? primary-side sensing technology eliminates opto-isolator and simplifes design tight led current regulation supports wide led output voltage range multiple protection features: x led open-circuit and short-circuit protection x over-current protection x current sense resistor short-circuit protection x ac line over-voltage/frequency protection x internal junction temperature-based over- temperature protection IW3630 ac/dc digital power controller for high power factor analog and 0-10v dimmable led drivers rev.1.1 product summary ? 2016 dialog semiconductor www.dialog-semiconductor.com 27-jan-2016
