Semtech Expands its Automotive Platform for Power Management and Display Backlighting Applications

Semtech Corporation launched two new devices in its automotive-qualified products platform. The SC5012Q is a 4-channel, high-brightness LED driver for infotainment and navigation display backlighting, and the SC220Q is a 20-MHz buck regulator with X-EMITM Inductor Technology. Both products extend Semtech’s broad automotive-qualified product offering, which includes solutions for power management, RF/ISM, touch interface and transient voltage protection.

“These two AEC-Q100-qualified products offer automotive electronics designers uncompromised performance and rugged dependability,” said Andy Khayat, Senior Business Unit Director for Consumer Power in Semtech’s Power Management Group. “Whether it’s display backlighting or power conversion, Semtech is committed to providing the most advanced power management ICs in fully qualified automotive grade.”

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

Key Features of SC5012Q include: Wide VIN range: 4.75V to 45V; High VOUT range: up to 65V; Up to 68 LEDs (17 LEDs x 4-ch) at 150mA/ch; Ultra-wide PWM dimming range up to 10,000:1 at 100Hz; and package: 24-pin QFN (4x4x1mm).

The SC5012Q and SC220Q are available immediately 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.
