Supertex Releases High Power LED Driver for Luminaire Applications

Supertex SUPX, a recognized leader in high voltage analogand mixed signal integrated circuits (ICs), today introduced theHV9805, an LED driver IC, where the LED light source is arranged as a high voltage LED string in order to accommodate certain lamp form factors, while allowing for cost savings through less complicated cooling and optical arrangements. The driver includes a linear postregulator to provide a pure DC current drive, for flicker free light output. The linear post regulator also provides protection from line voltage transients.
