    ADDRESSES DIMMING, HEAT AND COST IN HIGH POWER SSL BULBS

    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
    capacitors.

    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
