The iW3600 is a single-stage, high-performance
AC/DC offline power supply controller for
dimmable LED luminaires. It applies advanced
digital control technology to detect the dimmer
type, which provides dynamic impedance to
interface with the dimmer and control the LED
brightness at the same time.
With advanced dimmer detection technology, the iW3600
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 iW3600’s cycle-by-cycle waveform
analysis technology allows for fast dimmer setting response.
When no dimmer is on the line, the iW3600 optimizes the
power factor and minimizes the current harmonic distortion
to the AC line. Furthermore, in no dimmer condition, output
current is regulated at nominal output current value over a
wide input voltage range.
The iW3600 operates the main power converter that delivers
current to the LED load in quasi-resonant mode to provide
high power efficiency and minimize electro-magnetic
interference (EMI). The commonly utilized converter
topologies for iW3600 are buck-boost and flyback. 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 thus eliminating the
need for an opto-coupler.
● Compatible with NEMA SSL6 dimming curve standard
● Multiple protection features that include:
xx LED open-circuit and short-circuit protection
xx Over-current protection
xx Over-temperature protection
xx Current sensing resistor short-circuit protection
● AC line over-voltage protection
The iW3600 minimizes the external components count by
simplifying the EMI filter with Dialog’s EZ-EMI® technology.
The intelligent dimmer detection technology minimizes the
bleeding power loss. Additionally, the digital control loop of
the iW3600 maintains stable overall operating conditions
without the need for loop compensation components.
3.0 Applications
Dimmable LED retrofit lamps up to 45W
● Dimmable LED luminaires up to 45W
