It’s said that the provider of analog, high bandwidth communications and Ethernet IC solutions, Micrel ,has released its new linear White LED (WLED) Drivers, MIC4801/MIC4802, designed to eliminate noise, minimize component count and simplify numerous designs.
The new drivers are single channel, constant-current sink LED drivers designed for architectural, landscape, and general LED lighting products.
They do not require an inductor.The high efficiency WLED drivers are designed to drive a single LED up to 600mA and 800mA respectively and based on the architecture that has no switching losses present in traditional charge pumps or inductive boost circuits.
Other important features include low dropout voltages which allow the LEDs to be driven directly from low voltage sources and thus eliminate switching noise/losses which accompany the use of boost circuitry.
the company also announced six channel, constant-current sink LED drivers MIC4811 and MIC4812 targeting billboard, marquee, instrument and other large, general-purpose LED displays earlier this month.
