Furthermore, the NCP1568 controller can implement ACF topology with proven super junction (SJ) FETs or with high performance gallium nitride (GaN) FETs. Through the inclusion of high voltage start-up a solution based on the NCP1568 requires few external components, reducing standby power consumption. Additionally, high frequency of operation enables reduction in passive component sizes, dramatically increasing power density. Its ability to seamlessly transition to discontinuous conduction mode (DCM) further improves efficiency in light load conditions, resulting in standby power levels of less than30milliwatts (mW). This also allows power supply designers to pass worldwide efficiency regulatory standards. Adaptive ZVS frequency modulation provides a variable output voltage that optimizes USB-PD and Quick Charge implementation. Housed in a small TSSOP-16 package, the NCP1568 includes a variety of protection features. The quiet skip feature eliminates audible noise during operation, an essential requirement for indoor power adapter applications. The NCP51530A/B are 700 volt (V) high frequency high-side and low-side drivers for directly driving two N-channel power MOSFETs in high performance power applications. A particular feature is the fast dynamic response; a 30 nanosecond (ns) propagation delay is ideal for high frequency operation while the 5 ns propagation delay matching ensures market leading efficiency performance. The device provides a very robust solution with high dv/dt immunity (up to 50 V/ns) and negative transient immunity. It is available in an SOIC-8 or DFN-10 package, with the latter offering improved creepage distances and an exposed pad. An AEC-Q100 qualified version is available in an SO-8 package for demanding automotive applications. Commenting on the new releases, Ryan Zahn, Director of Marketing and Applications for the AC-DC Business Group at ON Semiconductor said: “This solution represents a significant step forward in design for modern power adapters and battery chargers. Advanced features and flexible operation in the NCP1568 ACF controller deliver excellent efficiency, while utilizing SJ FETs, and requiring few external components,

customers can continue to push the boundaries of high resolution image capture without sacrificing the image quality their applications require.” Engineering grade versions of the KAI-43140 are now available, with production versions planned for early 3Q18. The KAI-43140 is available in a ceramic PGA package, and is offered in monochrome, Bayer Color, and Sparse Color configurations. To help customers in the development of new camera designs incorporating the KAI-43140 and other image sensors from its portfolio, ON Semiconductor offers kits that support full evaluation including still image and video capture, region of interest (ROI) readout and pixel binning. Other custom test functions can also be configured. Customers can purchase an evaluation kit, or enquire about an on-site demonstration of the KAI-43140, by contacting their local ON Semiconductor sales representative.

Smallest 65W USB-PD Adapter Solution Using Industry Standard Super Junction FETs from ON Semiconductor ON Semiconductor (Nasdaq: ON), driving energy efficient innovations, has introduced a new solution for world class, high-density power adapters for notebooks, tablets, and other portable devices that require compatibility with the USB Power Delivery (USB PD) or Qualcomm Quick Charge™ specifications. The solution, which includes multiple patents pending, comprises the NCP1568 active clamp flyback (ACF) controller and a corresponding high-speed, half-bridge driver – the NCP51530. This results in a 65W USB-PD compliant adapter with a 30W/in^3 power density while operating at 94.5% peak efficiency. The NCP1568 is a highly-integrated AC-DC pulse width modulation (PWM) controller that implements an
