LID-PC-R101B is a constant current IC of supplying current to a load regardless of an input voltage variation. PC-R101A also includes
a compensation circuit of an input power for input voltage change
as well as a switching circuit by a LED group for the achievement
of high power factor (PF). It is the reliably stable and high
efficient LED driver for the safety of LED optical components sensitively affected by changes of voltage and current.
- Wide input range : maxium AC 300V
- LED protection by constant current driving and power compensation
- Drive max. 40W @220V, max.30W @110V in 25x30x1.6mm metal
- Adjustable efficiency and power factor by LED array and group
- Tap switching structure to implement high power factor
- 83% typical efficiency, minimum power factor 0.95 using 1 tap
- No EMI issue
- Small package MLF 20 pin, 7mm x 7mm
- Implementation of light and slim lighting fixture by minimizing
- Various kind of LED lighting
- Small size LED lighting - Down light, Bulb, etc.
LID-PC-R101B is designed with our uniquely and innovative LED AC
direct technologies (Our patent No.:KR0943656,KR0942234,
PCTKR2009-005333, PCTKR2009005334) without usage of any
complicated circuit, big capacity of inductor or condenser as used in
general SMPS or AC/DC convertor, It obviously provides longer lifetime
than LEDs due to the same manufacturing process of LED chips
(Especially for the juction tempererture, our IC can resist higher temperature than LED chips) as well as no usage of passive components badly affecting a lifetime of products with LEDs.
It can perform above 99% of power factor by optimizing switching tap
of LED group as optionla.
To improve a power factor, LID-PC-R101B is to be made up of three
different direct N LED groups and it can be done by connecting(N-1)
tab points out of N LEd groups. Furthermore, LID-PC-R101B has additional features to protect LED overload and reduces variation of
luminance through an internal power compensation circuit in case that
a unexpected input voltage peaks above 130% of a rated voltage.
It can support up to 30W output power at 220V/230 of a rated voltage and 20W output power at 110V/100V/120V of a rated voltage
along with 83% of efficiency as minimum.
