Driver drives LED efficiency
STMicroelectronics has introduced a new white LED driver with specific features for small LCD module backlight and high efficiency white LED power supply for portable applications.
The 2 x 350W Class-TT digital amplifier is designed for the consumer electronics market.
DPPT incorporates a 1bit sigma-delta digital to analogue convertor with a sampling frequency of 50MHz together with proprietary signal processing algorithms to provide uncompromised fidelity and unsurpassed power efficiency.
New designs have shown that this two-channel digital audio amplifier driver combined with a range of external power FETs can deliver up to 2 x 350W of power into 4ohm at 0.1% THD+N.
The TA3020 is the perfect alternative to conventional analogue amplifiers in the 100W, 8ohm A/V receiver market delivering 0.03% THD+N at an efficiency of 95%.
This level of performance opens new possibilities for reducing the size of these A/V receivers or radically changing the shape of this market by allowing A/V receiver functionality to be incorporated with other home entertainment functions to create new classes of products.
In a bridged configuration the TA3020 can provide an impressive 1200W.
Profusion is now marketing this unique IC into the UK and European audio market and sees it as a superb opportunity for audio manufacturers to develop new efficient amplifier designs.
The new developments open tremendous opportunities for companies to create new classes of home entertainment products.
The digital nature of Class-T amplifiers will enable an end to end digital solution from the proliferation of digital source material like DVDs, SACDs, MP3 and future digital streaming media formats all the way to the speaker.
