iW3662 uses Dialog's patent-pending digital control technology to optimise
compatibility with virtually any transformer (electronic or magnetic), to
loads as low as 4W
London UK, 05 February 2015 - Dialog Semiconductor plc (FWB:DLG), a
provider of highly integrated power management, AC/DC power conversion,
solid state lighting (SSL) and Bluetooth(R) Smart wireless technology,
today announced its entrance into the MR16 dimmable solid state lighting
(SSL) market with an innovative LED driver designed to solve transformer
and dimmer compatibility issues in challenging, low-voltage lighting
applications. The iW3662 uses Dialog's patent-pending digital control
technology to optimise low-voltage SSL bulbs for compatibility with
virtually any transformer (electronic or magnetic), even in lighting
applications with output power as low as 4W.
The greatest challenge in designing low-voltage MR16 LED retrofit bulbs is
the installed base of AC step-down electronic transformers, which are not a
good match for LED lighting. MR16 halogen lamps require transformers to
convert the standard electric line voltage down to 12VAC. Most low-voltage
halogen lighting systems use small, inexpensive electronic transformers to
perform this conversion. These transformers are designed to power resistive
loads and can typically require a minimum load of 20W. While this load is
easily provided by 50W halogen lamps, an equivalent LED MR16 lamp drawing
8W struggles to latch the transformer, with lower wattage bulb replacements
often completely failing.
The iW3662 LED driver solves this MR16 transformer compatibility problem
with patent-pending control technology that uses advanced digital analytics
to detect installed electronic transformers and dynamically increases the
peak loading to latch the transformer, even during low dimming ranges,
while maintaining the high efficiency expected from SSL LED bulbs. The
iW3662 includes detection for magnetic step-down transformers as well to
automatically switch in a compatible loading mechanism for these older
models.
The iW3662 dimmable MR16 SSL LED driver also uses digital technology to
provide exceptional dimmer compatibility (both TRIAC and digital dimmers)
and dimmer performance, with either electronic or magnetic transformers. It
delivers smooth flicker and shimmer-free dimming down to 5% of measured
light.
"Dialog is the definitive leader in digital control technology for SSL
lighting, with LED driver solutions for applications ranging from small
form-factor retrofit bulbs to commercial lighting ballasts," said Davin
Lee, Senior Vice President and General Manager of the Power Conversion
Business Group at Dialog Semiconductor. "The one remaining portion of the
market we had not addressed was the low-voltage, dimmable MR16 segment,
where our customers experience transformer and dimmer compatibility issues
with existing LED driver solutions. Our innovative iW3662 builds on our
digital control expertise with new intellectual property developed
specifically for the low-voltage SSL lighting market."
The iW3662 is seeing broad industry adoption with Sengled Lighting being
one of the first early adopters to offer a new generation of MR16 bulbs to
the market.
"As a global leader in high quality, energy-saving green lighting
solutions, Sengled is dedicated to bringing the most innovative SSL
products to the market," explains Johnson Shen, Founder and President at
Sengled Lighting. "The challenge with low-voltage, dimmable MR16 lighting
is compatibility with the existing infrastructure of transformers and
dimmers. Dialog's new iW3662 LED driver enabled us to easily, elegantly and
cost effectively solve these issues and enabled us to deliver the highest
quality dimmable MR16 LED bulbs that allow consumers to seamlessly replace
halogen bulbs today."
Designed for low-voltage AC and DC inputs, the iW3662 offers either
single-stage or two-stage operation. This simplifies design and reduces
development time by allowing designers to specify one part across multiple
low-voltage LED replacement bulb applications, as well as high-voltage
chip-on-board (COB) LED modules up to 8W.
The advanced control circuitry in the iW3662 helps designers reduce their
bill of materials (BOM) cost by enabling the use of low-cost, off-the-shelf
inductors, while the high-frequency 1MHz switching supports the use of
smaller, less-expensive external components.
The iW3662 integrates Dialog's patented over-temperature protection (OTP)
de-rating technology to address LED bulb lifetime issues caused by
excessive heat. OTP technology monitors the temperature inside the sealed
SSL bulb and seamlessly dims light output if the temperature rises above a
safe operating threshold, then restores brightness as temperature falls.
This results in cooler operation, avoids exceeding the temperature rating
of the electrolytic capacitors, and helps ensure a predictable and safer
bulb operating life.
