ON Semiconductor Addresses Modern Power Design Challenges at Applied Power Electronics Conference 2013
Cutting-edge digital AC-DC PWM controllers, motor drivers and IGBTs to be demonstrated by the company at industry’s premier power electronics show
LONG BEACH, Calif.–(BUSINESS WIRE)– ON Semiconductor (Nasdaq: ONNN), driving innovation in energy efficiency, will showcase its latest power efficient product advances at APEC 2013, March 17-21, 2013, in Long Beach, California. The new devices are designed for boosting performance and simplifying the design of offline power supplies, AC lighting infrastructure and motor control systems.
Targeted for high efficiency, compact, switch-mode power supplies for power adaptors, the NCP1937is a quasi-resonant (QR) flyback controller device with power factor correction (PFC). This is the first AC-DC device utilizing a hybrid digital core architecture enabling higher efficiency, increased flexibility and easier system design implementation. The device incorporates all the features necessary for building a robust and compact PFC stage in combination with a QR flyback stage, while minimizing the number of external components. The quasi-resonant current-mode flyback stage features a proprietary valley-lockout circuitry, ensuring stable valley switching. It has wide voltage range spanning 9 volts (V) to 30 V, plus built-in over-voltage protection, and a skip mode operation which enables higher efficiency in light load conditions. The NCP1937 will be demonstrated in an 85 watt (W) Notebook Adapter showcasing the industry’s leading <10 milliWatt (mW) no load standby power.
The NCP1255/NCP1254 is a fixed frequencyPWM controller designed for applications requiring peak power capability. Offered in SOIC-8 and TSOP-6 packages, it operates with a fixed 65 kilohertz (kHz) switching frequency with the ability to scale the frequency up to 130 kHz based on output load requirements. In light load conditions with the power on the secondary side decreasing, the IC automatically folds back its switching frequency to a minimum level (26 kHz). The inclusion of adjustable over-power protection and adjustable brown-out protection functions make this device ideal for products requiring peak-power capabilities such as printers and ultrabooks. The NCP1255 will be demonstrated in a 15 W nominal 55 W peak power printer adapter.
For LED power supply applications, the high functional integration of theNCL30081 PWM controller IC minimizes the number of external components required for AC powered LED lighting designs. It operates in a quasi-resonant mode to enhance overall efficiency and provides precision regulation of the LED current from the primary side. Dispensing with the need for secondary side feedback control, as well as the associated optocoupler and …read more

Key Research Confirms Toshiba’s 13-year Long Market Leadership in the A3 MFP Market in China
SHANGHAI–(BUSINESS WIRE)– Toshiba, the global leaders in printing and imaging products, solutions and services, has for the 13th consecutive year retained its position as market leader in the A3 MFP Product Category in China, according to regional industry analysts Key Research Company.
Facts and Figures
“China‘s economic growth could be over 8 percent this year. China‘s economy supports a very large part of global demand,” Senior Industry Analysts told Reuters recently. Full year growth in the world’s second biggest economy rose to 7.8 percent in 2012.
Interestingly, the A3 MFP market in China stood at 507,300 units in 2012, a 4 percent decline from 2011 according to Key Research. Although the Color MFP devices grew 19 percent in sales units, the monochrome devices suffered a decline of 6 percent compared to last year.
Toshiba maintained its leadership in the China A3 MFP market with a market share of 17.9 percent, ranking unrivalled at No. 1 since 2000.
Leading market analysts in the APEC region Key Research put Toshiba at the top of the league table of MFP solution providers in China, the company now for the 13th year in a row confirming is strong market position in the world’s second largest economy.
Toshiba TEC Strategy
To further strengthen its market leadership in the MFP market in Asia, Toshiba TEC will soon roll out a new, compact line of the award-winning e-STUDIO MFP series. Toshiba will combine the brand’s traditional virtues of reliability and long life cycle with attractive price points.
According to market analysts, the region’s economies continue to grow at a high rate and Toshiba TEC is extremely well-positioned to meet the demand of this booming Small and Medium-sized Businesses market segment (SMB). “The company is proud to sign for a strong value proposition and a nationwide distribution network aimed at delivering top service to customers in Asia throughout the long product lifecycle of Toshiba TEC MFP solutions,” Isao Sugehara, President, Toshiba TEC China said.
Toshiba TEC’s portfolio of monochrome MFPs in combination with a strong offering of new color MFP solutions allows users from industries including, agriculture, manufacturing, construction, real estate, banking and insurance, transportation and logistics, …read more

Fairchild Semiconductor Highlights “Source-to-System” Power Efficiency at APEC 2013
Latest Power Design Solutions Focus on Design Needs
SAN JOSE, Calif.–(BUSINESS WIRE)– DuringAPEC 2013, March 17-21, 2013, in booth 209 at the Long Beach Convention Center, Long Beach, Calif., Fairchild Semiconductor, (NYS: FCS) puts the focus on engineers, and invites visitors to share their design challenges with power experts to find solutions that support their overall success.
As a leading global supplier of high performance power and mobile semiconductor solutions, Fairchild will be available to discuss the latest “source-to system” power efficiency solutions intended to meet critical design challenges in lighting, DC-DC conversion, industrial power and motion control.
One area of focus at the show is on motor control applications, where designers are now moving away from the traditional universal, or AC motor design, to a more sophisticated brushless DC (BLDC) motor or permanent magnet synchronous motor (PMSM) design. However, choosing either of these methods can be challenging if the designer has limited access to advanced, complex motor control algorithms. This can lead to significant spending of research and development resources and longer design times. To help designers with these cost and software burdens, Fairchild developed the FCM8531 analog and digital integrated motor controller. The FCM8531 is a tailored configurable solution complete with user guides, reference designs, and evaluation boards that help motor control designers shorten time-to-market and minimize software design efforts.
Other exhibits and demonstrations available for discussion include:
- Lighting: Power conditioning, power conversion and load control solutions for LED lighting applications from 3W – 200W, including dimmable, non-dimmable, isolated, non-isolated, single and multi-string reference designs.
- DC-DC Conversion: Integrated ICs as well as discrete solutions that offer improved thermal resistance, smaller sizes and greater reliability resulting in leading power supply efficiencies.
