Apple Streaming Music Service May Launch Soon

Leave a comment

Rumors of Apple’s streaming music service to compete with services like Pandora have grabbed the spotlight again, and Ars Technica reports that the Cupertino company is closer than ever to reaching deals with major record labels.

Sources told CNET that the radio option is a gambit to boost download sales through iTunes, and will be designed with “quick-buy” features. The Cupertino company is also in the midst of making headway in negotiations with the so-called “Big Four” record labels, inching closer to deals with Warner Music and Universal Music Group but still working with EMI and Sony Music. There’s plenty of steps ahead before a radio station system is ready — namely agreements with music publishers — but sources say Apple is on the move.

Fairchild Semiconductor’s Power Supply WebDesigner Now Provides CCM, Non-Isolated PFC Buck and Buck LED Driver Designs in Under a Minute

New Modules Provide Optimal Design with Complete Schematics, Inductor Design and Bill of Materials

SAN JOSE, Calif.–(BUSINESS WIRE)– Fairchild Semiconductor (NYS: FCS) , a leading global supplier of high performance power and mobile semiconductor solutions, has enhanced Power Supply WebDesigner – an online design and simulation tool that provides complete designs in under a minute – to include complete continuous conduction mode (CCM), non-isolated active PFC buck and buck LED driver designs.

From user-specified design inputs, the Power Supply WebDesigner (PSW) tool allows designers to choose all the components used in a design or have the tool automatically recommend the design values – providing Fairchild part numbers where applicable. PSW can automatically recommend design values, or allows the user to evaluate their own component choices.

While using the tool, designers can accept default recommended values, or spend time optimizing the important details to their unique design needs. Designers can get quick, accurate estimates on design performance, and refine design choices as they go. The tool also allows them to spend the time to perform detailed simulation analysis and learn the insights of how their design and its hardware prototype will work with higher degree of confidence.

When a design is complete, PSW creates a BOM which can be sent to their procurement department or instantly procure the components online, saving time on documentation or sourcing parts elsewhere. Additionally, they can save their design for future reference or pass the design on to other engineers.

Using the Power Supply WebDesigner tool provides the inexperienced designer a quick guided design, while the experienced designer can take their requirements and further customize critical design factors.

Updates:

  • Fairchild’s latest CCM buck and non-isolated PFC buck LED drivers are added options for PSW users, supporting Fairchild’s family of LED drivers.
  • First-available LED online tool designed to help design EMI filters, predict power factor (PF) and total harmonic distortion (THD).
  • PSW features have been extended to include the special driver requirements of low power (≤ 20W) …read more

Power Integrations’ New PI Expert Suite9.0 Power Supply Design Software Supports LED Lighting

Improves productivity with enhanced schematics-manipulation tool and BOM output to design-fulfillment distributors

SAN JOSE, Calif.–(BUSINESS WIRE)– Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today announced that the latest version of its popular power supply design software, PI Expert Suite 9.0, now includes support for its LinkSwitch™-PL and LinkSwitch-PH LED-driver ICs and its recently introduced TinySwitch™-4 off-line switcher IC family. Version 9.0 includes an enhanced schematics-manipulation tool. It also enables designers to upload the resulting BOM from the auto-generated schematic layout to selected, leading design-fulfillment distributors.

PI Expert Suite 9.0
 improves the productivity of power supply design teams by greatly reducing the time to first prototype and by slashing the number of prototype iterations required to reach a finished product. The software now includes support for solid-state-lighting products, enabling LED designs to be optimized for CC, dimming and harmonic emissions. As with previous-generations, PI Expert Suite 9.0generates a complete schematic of the power supply and offers power transformer optimization techniques, even specifying the transformer design and offering links to wound component manufacturers. A heatsink calculation tool provides the designer with an estimation of the thermal design requirements for a new power supply which may be used to guide layout and mechanical prototyping decisions – avoiding iterations and wasted time. Enhanced PCB layout recommendations based on the IC device and package chosen allow the designer to minimize trace-induced EMI and board area, and also maximize electrical noise immunity and surge tolerance.

Comments Peter Vaughan, director of applications engineering at Power Integrations: “LED-lighting engineers face difficult electrical, mechanical and thermal challenges as they continue to develop innovative solid-state-lighting products. PI Expertremains the only comprehensive PSU design tool capable of satisfying the demands of both experienced and new power supply designers alike. With support for our LinkSwitch-PL and LinkSwitch-PH ICs, they can achieve a better, more efficient solution in a shorter time.”

Semtech Announces Expansion of its Automotive Qualified Product Platform for Power Management and Display Backlighting Applications

SC5012Q and SC220Q broaden Semtech’s AEC-Q100 automotive-qualified power offering

CAMARILLO, Calif.–(BUSINESS WIRE)– Semtech Corporation (NAS: SMTC) , a leading supplier of analog and mixed-signal semiconductors, today launched two new devices in its automotive-qualified products platform. The SC5012Q 4-channel, high-brightness LED driver for infotainment and navigation display backlighting, and the SC220Q 20MHz 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

  • 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
