iW3600 offers wide 1% to 100% dimming range with low pop-on current < 5%
of light output; Built-in configurable temperature derating for predictable
operating life

London, UK, 31 March 2014 - Dialog Semiconductor plc (FWB:DLG), a provider
of highly integrated power management, AC/DC, solid state lighting and
short-range wireless technologies, today introduced its latest single-stage
LED driver to address dimming performance, heat and cost in high power,
dimmable solid state lighting (SSL) applications. The new 45W output iW3600
seamlessly dims from 100% down to 1% of measured light with virtually no
dead travel and offers low pop-on current to turn light on at very low
dimmer levels (< 5% of light output).It also uses Dialog's patented,
configurable over-temperature protection (OTP) derating to tackle LED bulb
lifetime issues caused by excessive heat, while its single-stage, digital
design lowers Bill Of Material (BOM) costs for lighting OEMs.

Designed for retrofit bulbs including external, dimmable lighting ballast
drivers and A19, PAR and T8 bulb replacements used in existing phase-cut
dimmer installations, the iW3600 incorporates Dialog's patented intelligent
dimming control to provide compatibility with a wider range of dimmers,
including TRIAC, digital and universal dimmers. This technology uses
digital analytics to query the dimmer and applies algorithms that
automatically adapt to the dimmer type.

Dialog's patented over-temperature protection derating technology addresses
LED bulb lifetime issues caused by excessive heat in retrofit bulb
installations. Most power ICs are designed with thermal shutdown, which
simply shuts the IC down in high temperature environments. This procedure
protects the IC, but not the LED driver circuit, since most control IC
shutdown occurs well above safe operating temperatures for electrolytic

The iW3600's built-in configurable temperature derating technology monitors
the temperature inside the sealed SSL bulb and, in high temperatures,
automatically reduces current drive to the LEDs in small, virtually
imperceptible increments, then seamlessly restores brightness as
temperature falls. This results in cooler operation in low airflow bulb
installations, avoids exceeding the temperature rating of the electrolytic
capacitors, and helps ensure a predictable and safer bulb operating life.

The iW3600 meets or exceeds global regulations for power quality and
efficiency with low total harmonic distortion (THD) < 20%.and high power
factor (PF) > 0.92.
