ON Semiconductor to Demonstrate Highly Integrated Controllers that Support Robust and Efficient End Product Designs at APEC  Chinese Japanese

New PFC and PWM controllers incorporate functionality and protection features that reduce component count and enhance safety















NCP1565Highly Integrated Dual-Mode Active Clamp PWM Controller
.

Applied Power Electronics Conference (APEC) – Booth 806 – FORT WORTH, Texas – March 17, 2014 – ON Semiconductor (Nasdaq: ONNN), driving energy efficient innovations, will be demonstrating its latest integrated controllers at this year’s APEC in Fort Worth, Texas, March 16 - 20. The show, which is the premier North American event focusing on applied power electronics, provides the ideal forum for ON Semiconductor to showcase its broad portfolio of devices that help enable the design of efficient, safe, and cost-effective power electronics across multiple sectors including networking, computing, consumer and portable electronics, white goods, and solid state lighting.

In the demonstration of the NCP1565 dual-mode active clamp PWM controller, a telecom industry 100 watt (W) quarter brick will be loaded continuously in a triangular fashion from 0.1 ampere (A) to 10 A to 0.1 A. This will show the adaptive zero voltage switching (ZVS) feature of the device’s dual-mode active clamp pulse width modulation (PWM) controller where dead-time varies with load to achieve the optimum ZVS point. This highly integrated device is targeted at next generation high-density, high performance, and small to medium power level isolated dc-dc converters used in the networking industries. It can also be used in 42 volt (V) automotive applications. The NCP1565 conveniently integrates all necessary control and protection functions that are required to implement an isolated active clamp forward converter or asymmetric half-bridge converter.

The NCP1615 power factor controller will also be featured in a demonstration. This high voltage, power factor correction controller (PFC) is designed to drive PFC boost stages based on an innovative current controlled frequency foldback (CCFF) method and provides a rugged and extremely efficient solution for applications in computer power supplies, flat screen TVs, and LED lighting and ballasts. An integrated high-voltage start-up circuit along with numerous other built-in features eliminates the need for a number of external components helping to simplify design, enhance reliability, and reduce cost. This demonstration will show how the NCP1615 operates in a zero power consumption state when no load is applied, thus creating a safe environment for the end user by discharging the EMI filter capacitors when the power source is disconnected. These two features enable easy, robust, and efficient designs.

“APEC is an important landmark in the global electronics industry calendar,” said Shane Chilton, senior director, AC DC Power Conversion Division at ON Semiconductor. “ON Semiconductor’s innovative and growing portfolio of highly integrated power devices helps designers in a wide and diverse range of industry sectors achieve their targets for efficiency and performance, while also being robust and cost-effective.”
