Fully Protected LED Driver suits backlighting applications.
2013-08-26 14:32:07| Industrial Newsroom - All News for Today
Step-up converter APE1612-3, capable of driving up to 8 white LEDs in series for backlighting applications, uses current mode, 1.2 MHz fixed frequency architecture to regulate LED current, which is set using external current sense resistor. While 300 mV feedback voltage reduces power loss and promotes efficiency, 200 Hz to 200 kHz range enables use in PWM dimming. Over-voltage, UVLO, current limiting, and thermal shutdown protection features are standard. This story is related to the following:Dimmable LED Drivers | Buck/Boost Converters

Philips voluntarily recalls 99,000 LED bulbs due to shock hazard
2013-08-23 20:31:35| Extremetech
Last week, Philips issued a voluntary recall of 99,000 LED bulbs because of the rather unsettling risk of "shock hazard." The recall hasn't gotten much attention yet but, as with all consumer electronics safety recalls, it's worth knowing about and worth understanding.
