PR4403 drives and controls white LEDs out of one single battery charged by solar cells. Using the ON/OFF pin, the LED driver is suitable for operating solar lamps that switch on after sunset automatically. A solar cell in combination with a recharchable battery enables a on-going operation. An additional photodiode becomes dispensable.

PR4101 is a buckdriver for up to 40V input voltage. Its versatility and its dimming input make it ideal for halogen lamp replacement and general lighting. PR4101 is offered in SO-08 and SO-14 package, as well as a smaller variant in a tiny SOT23-5L package. Versatility and high power are key features of these LED drivers, which can also be used as proven standard cells in an ASIC project.

PR4401 andPR4402 are LED boost converters in a tinySOT23 package that drive white LEDs from a single battery cell. Output currents of 20mA (PR 4401) and40mA (PR 4402) can be achieved. The only other component needed is an inductor. A cleverly devised control circuit produces a constant output current. Read more...More Product Announcements from PREMA Semiconductor GmbH
BD9408FV is a high efficiency driver for white LEDs and it is designed for large LCDs. BD9408FV has a boost DC/DC converter that can supply appropriate voltage to the light source of LEDs series array. Read more...More Product Announcements from ROHM Semiconductor GmbH
Littelfuse, Inc. today introduced a series of PLEDs with an ultra-low holding current (just 21mA) that makes the ballast drivers widely used in the output of fluorescent tubes compatible with modern replacement LED strings or tubes. This eliminates the need to scrap otherwise still-working ballasts when replacing fluorescent lighting tubes with LED strings or tubes. Read more...More Product Announcements from Littelfuse, Inc.
