NXP mains-dimmable
drivers and controller
for LED lighting
SSL21082(A)/84(A)
& SSL2129A
Design LED lights with best-in-class
dimmer compatibility per watt
These`best-in-class`mains-dimmable`SSL`GreenChip`ICs,`suitable`for`use`in`isolated`and`non-
isolated`compact`LED`driver`topologies,`deliver`excellent`efficiency`and`reduce`system`cost.
Key features
Applications
``Superb`mains-dimmable`LED`driver`solution`(both`leading`
and`trailing`edge`phase`cut`dimmers)
``Buck`driver`ICs
``Dimmable`retrofit`LED`lamps
``Dimmable`driver`modules`for`LED`lighting
-`Integrated`300`V`MOSFET`(SSL21082,`SSL21082A)
-`Integrated`600`V`MOSFET`(SSL21084,`SSL21084A)`
``Flyback`or`buck`controller`IC
The`NXP`SSL2129A`is`a`high-efficiency`controller`IC`for`
superior`dimmable`LED`lighting`solutions`that`typically`
operates`in`the`lamp`power`range`of`4`to`25`W.`
-`Controller-only`with`external`MOSFET`(SSL2129A)
-`Supports`tapped-buck`topologies`to`extend`the`Vf`LED`
range
The`straightforward`design`produces`a`cost-effective`yet`
compact`application,`suitable`for`use`with`GU10`and`PAR16`
formats.`A`low-cost`bipolar`bleeder`circuit`supports`a`best-
in-class`dimmer`compatibility`performance`for`mainstream,`
single-stage`LED`driver`applications.
``Highest`efficiency`due`to:`
-`Power-efficient`boundary`conduction`mode`
-`Start-up`JFET
``High`power`factor`(>0.9)
``Full`range`of`internal`protections
``Compatible`with`wall`switches`with`built-in`indication`light`
during`standby
The`SSL2129A`can`be`configured`in`either`buck`(non-isolated)`
or`flyback`(isolated)`topologies`at`mains`supply`voltages`of`100`
to`120`V`or`230`V.
``“A”`versions`without`short`winding`protection
As`part`of`the`same`dimmable`product`family,`NXP`also`offers`
driver`ICs`with`an`integrated`MOSFET.`The`SSL21082(A),`with`a`
300`V`MOSFET,`is`designed`for`applications`in`the`100`to`120`V`
range,`while`the`SSL21084(A),`with`a`600`V`MOSFET,`is`for`use`
with`230`V`mains`supply`voltages.`Both`ICs`support`dimmable`
Key benefits
``Benchmark`dimmer`compatibility`per`watt
``Compact,`single-stage`LED`driver`solution`lowers`eBOM`
cost
``Optimized,`high-efficiency`operation`improves`total`lumen`
output`per`watt,`lowering`energy`consumption`further
LED`lamp`powers`up`to`15`W,`while`easing`the`design-in`
process.
The`second`aspect`is`controllability,`which`refers`to`how`
precisely`the`user`can`control`and`reduce`the`lamp’s`light`output.`
LED`driver`applications`based`on`NXP’s`dimmable`SSL`driver`ICs`
show`a`great`dimmer`compatibility`per`watt`at`a`very`high`power`
merit`factor.`Dimmer`compatibility`per`watt`not`only`depends`
on`IC`features,`but`also`on`the`system`implementation.``NXP’s`
application`expertise,`know-how`and`customer`support`are`of`
crucial`importance`in`designing`a`mains`dimmable`LED`driver`
solution.
When`comparing`the`performance`of`dimmable`LED`driver`
solutions`operating`at`the`same`lamp`power`levels,`dimmer`
compatibility`per`watt`is`a`more`meaningful`parameter`than`
dimmer`compatibility`alone.`
NXP`determines`lamp`performance`from`the`end-user`
perspective`by`using`a`combination`of`these`criteria,`resulting`
in`a`power`merit`factor`that`is`based`on`two`aspects.`The`first`
aspect`is`stability,`which`refers`to`how`well`the`lamp`avoids`
visual`disturbances`like`flicker,`shimmer`and`flashing.`
The`long`life`time`of`LED`lamp`solutions,`in`combination`with`
the`impressive`energy`savings,`result`in`significant`reduction`
of`energy`usage`(supporting`a`green`environment`at`very`low`
energy`cost)`and`low`maintenance`cost.
