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 ...
