iW3616
AC/DC Digital Power Controller for
High Power Factor Dimmable LED Drivers
1 Description
The iW3616 is a two-stage, high-performance AC/DC offline 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 Dialog’s unique digital
FlickerlessTM technology to eliminate visible flicker 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 iW3616’s 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 efficiency and minimize electro-magnetic interference (EMI). It uses Dialog’s patented
PrimAccurateTM 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 filter 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.
