Power Integrations (Nasdaq: POWI), a leader in high-voltage integrated circuits for energy-efficient power conversion, recently introduced HiperPFS, a family of power factor correction (PFC) controllers with integrated high-voltage power MOSFETs. The unit's innovative control design enables optimum efficiency at light loads. Compared to the design using separate MOSFETs and controllers, the HiperPFS device not only significantly reduces component count and board area, but also simplifies system design and enhances reliability. The HiperPFS unit is available in a tiny, low-profile eSIPTM package for PFC applications from 75 W to 1 kW.
HiperPFS simplifies compliance with new and developing energy efficiency standards in the board market space in applications such as computers, LCD TVs, notebooks, appliances, pumps, motors, fans, printers and LED lighting. Power Integrations' innovative variable frequency operation continuous conduction mode (VF-CCM) maintains a low average switching frequency, minimizes switching losses, and also changes the switching frequency to suppress EMI, which is present in continuous conduction mode. The challenge of the solution. Systems using HiperPFS typically save the core size of both boost inductors and common-mode EMI noise-suppressing inductors, reducing overall system size and cost. The regulations have been implemented in Europe, the United States and other regions where high power factor is enforced for many electronic products, requiring power above 75 W and lighting products above 5W.
HiperPFS devices are available now, and like Power Integrations' other power conversion product families, HiperPFS also includes comprehensive protection features such as integrated soft-start, fault and overload protection, and hysteresis replies overtemperature protection.

2 In 1 Laptop
Do you know the difference of Yoga Laptop and 2 in 1 laptop? No. 1 is yoga notebook with 360 flip rotating absolutely; No.2 is laptop yoga slim is just like normal Education Laptop-connecting screen with keyboard, but 2 in 1 laptop tablet with pen is separately, you can use the monitor part as a window tablet. In one word, every intel yoga laptop have all the features and function of tablet 2 in 1 laptop except separated screen and keyboard. From the cost, windows yoga laptop is much higher than 2 in 1 type., cause usually former with more complicated craft and quality.
What other products you mainly produce? It`s education laptop, Gaming Laptop, engineering laptop, Android Tablet, Mini PC and All In One PC. You can see more than 5 different designs on each series, believe always have right one meet your special application or your clients demands. Therefore, what you need to do is just to get all the requirement details from your clients, then share the complete information with us, then we can provide the most suitable situation.
Of course, you can also call or email or send inquiry of what you need, thus can get value information much quickly.
