Semtech Corp. has rolled out a couple of devices that extend the firm's automotive-qualified product offering. The SC5012Q 4-channel, high-brightness LED driver targets infotainment and navigation display backlighting, while the SC220Q 20MHz buck regulator features the X-EMI inductor technology.

The SC5012Q drives up to 68 high brightness 150mA LEDs and offers advanced analogue/digital dimming of up to 10,000:1 ratio that gives automotive LCD displays an extended range of brightness options for varied driving conditions, stated Semtech. The SC220Q provides high-efficiency DC/DC buck conversion while allowing designers to draw their own inductor on a standard PCB board to minimise board height and greatly reduce EMI noise. These benefits enable embedded power supplies in low profile applications such as rearview mirrors and backup cameras, the company added.

The SC5012Q features 4.75-45V VIN range, VOUT range up to 65V and is available in a 4 x 4 x 1mm 24-pin QFN package.

The SC220Q touts 2.7-5V VIN range, output current up to 650mA, 20MHz switching frequency, and is available in an 8-pin SOIC package.

The SC5012Q and SC220Q are available in production quantities. The SC5012Q is priced at $1.54 each (ordering code SC5012QMLTRT) in 3,000 piece lots and the SC220Q is priced at $0.39 each (ordering code SC220QSTRT) in 2,500 piece lots. Evaluation boards are also available. Order codes are SC5012EVB and SC220EVB.
