The SC5012Q 4-channel, high-brightness LED driver for infotainment and navigation display backlighting and the SC220Q 20-MHz buck regulator with X-EMITM inductor technology expand Semtech’s electronics product offerings. Both feature performance and dependability: the SC5012Q drives up to 68 bright 150-mA LEDs from 4.75 to 45 V and offers advanced analog/digital dimming up to 10,000:1 ratio to extend brightness options for varied driving conditions. The SC220Q provides efficient dc-dc buck conversion from 2.7 to 5 V while allowing designers to draw on a standard printed circuit board to minimize board height and reduce noise. Benefits enable embedded power supplies in low-profile applications including rearview mirrors and backup cameras. Other suitable functions include audio/video/navigation, seatback infotainment, and LCD mirror displays.
