iW3689 AC/DC Digital Power Controller for Single-Stage High Power Factor Dimmable LED Drivers 1 Description The iW3689 is a single-stage, high-performance AC/DC off-line power supply controller for dimmable LED luminaires. It applies advanced digital control technology to detect the dimmer type, enabling it to provide dynamic impedance to interface with the dimmer and to control the LED brightness at the same time. With advanced dimmer detection technology, the iW3689 can operate with most wall dimmers including leading-edge dimmers (R-type or R-L type), trailing-edge dimmers (R-C type), and smart dimmers. In addition, the iW3689’s cycleby-cycle waveform analysis technology allows for fast dimmer transient response. In no-dimmer mode, the iW3689 operates the main power converter that delivers current to the LED load in quasiresonant mode to provide high power efficiency and low electro-magnetic interference (EMI). When there is no dimmer on the line, the iW3689 optimizes the power factor and minimizes the current harmonic distortion to the AC line. The commonly utilized converter topologies for iW3689 are buck-boost and flyback. The iW3689 uses patented PrimAccurate™ 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 thus eliminating the need for an opto-coupler. The iW3689 minimizes the external components count by simplifying the EMI filter with Dialog’s EZ-EMI® technology, and by integrating current sink, switching, and VCC charging circuit. Additionally, the iW3689 does not require an auxiliary winding, which eliminates the need for a custom inductor. The digital control loop of the iW3689 maintains stability over all operating conditions without the need for loop compensation components. The iW3689 maintains high performance wide-range dimming and achieves excellent dimmer compatibility with a simple application circuit. 2 Features ●● Isolated/non-isolated off-line 120VAC/230VAC LED driver up to 25W (Note 1) ●● Resonant control to achieve high efficiency (typical >85% without dimmer) ●● Wide line frequency range (from 45Hz to 66Hz) ●● Excellent AC line distortion immunity ensures quality of product under real-life circumstances ●● Meets IEC61000-3-2 current harmonic requirement ●● Over-temperature LED current foldback and shutdown ●● Total harmonic distortion < 20% with PF > 0.92 ●● Excellent dimmer compatibility ●● Tight LED current regulation (±5%) xx Leading-edge dimmer ●● Fast start-up (< 0.5s without dimmer) xx Trailing-edge dimmer ●● Multiple protection features that include: xx Digital smart dimmer xx LED open-circuit and short-circuit protection ●● Wide dimming range of 1% to 100% ●● Intelligent digital control integrates current sink and VCC maintenance function into power switching circuit ●● Advanced IC power management and voltage sensing enables the use of off-the-shelf inductor xx Current sensing resistor open circuit and shortcircuit protection xx Over-current protection 3 Applications ●● Dimmable LED retrofit lamps up to 25W (Note 1) ●● Dimmable LED luminaires up to 25W (Note 1) Product Summary www.dialog-semiconductor.com Rev. 1.11 1 of 6 18-Dec-2018 © 2018 Dialog Semiconductor iW3689 AC/DC Digital Power Controller for Single-Stage High Power Factor Dimmable LED Drivers - N + + L iW3689 1 VIN 2 CFG 3 VCC 4 GND VCB 8 VD 7 VS 6 ISENSE 5 + Figure 3.1 : iW3689 Typical Application Circuit Note 1 : For output power above 12W designs, care should be taken to verify the thermal and reliability constrains on the IC.
