IPS401 Datasheet, PDF (1/18 Pages) List of Unclassifed Manufacturers – High Efficiency, High Power Factor, Universal High Brightness WHITE LED Controller

IN-PLUG^® IPS401 Datasheet - Rev.11 - Universal WHITE LED Controller with 0.5V current FB voltage
IN-PLUG^® series: IPS401
High Efficiency, High Power Factor, Universal
High Brightness WHITE LED Controller
INTRODUCTION
– REVISION 11 –
DESCRIPTION
The IPS401 is the world’s first White LED controller
capable of driving one or more strings of up to 120
LEDs in series with high efficiency and power factor
correction. The IPS401 is the forerunner of a series of
Ics which will provide a means of implementing high
efficiency, long life, and reliable lighting systems for
public buildings, industry, homes, transportation
systems and secure installations. It is also the ultimate
solution for RGB backlighting, flat panel display
backlighting and automotive long life lighting and
energy saving requirements. Safety features of the
IPS401 include over voltage and over current
protection.
A host of novel features such as self-oscillating and
continuous mode of operation, PFC capability
together with exceptionally low power dissipation
make the IPS401 a truly breakthrough product which
will establish standards for future “green” lighting
technology.
In addition to the compliance with power factor and
line harmonics regulations, using a PFC offers other
advantages like:
• Reducing the utility bill by making the actual
power drawn from the line almost equal to the
apparent power paid to the utility company
• Allowing more power to be drawn from the wall
outlet or line circuit breaker without exceeding
the limits set by UL or other safety agencies.
