U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :POWI), the leading supplier of high-voltage analog integrated circuits used in power conversion, announced today the availability of a new product family enabling cost-effective switching power supplies for low power applications requiring tight output regulation. LinkSwitch-HF expands the company's current LinkSwitch product line of power conversion ICs. The devices offer designers a low cost and very energy-efficient replacement for regulated linear transformer and discrete power supply designs.
LinkSwitch-HF product is targeted towards applications such as battery chargers and appliances that require fault protection and accurate control of output voltage and current. By eliminating the separate bias winding on the power supply transformer, system component cost is reduced compared to competitive switcher designs. Additionally, switching characteristics of the IC's integrated high voltage MOSFET (Metal Oxide Semiconductor Field Effect Transistor) The most popular and widely used type of field effect transistor (see FET). MOSFETs are either NMOS (n-channel) or PMOS (p-channel) transistors, which are fabricated as individually packaged have been optimized to reduce electro-magnetic interference (EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. ), allowing conformance to international emission standards. A power supply design with very low line-frequency leakage current is possible, allowing safe use of a metal-encased mobile phone during battery charging.

Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air with simple on/off control, high voltage start-up, cycle-by-cycle current limit, hysteretic hys·ter·e·sis

The new product family also incorporates the company's EcoSmart(R) technology, dramatically reducing energy waste in standby and no-load conditions. In a standard AC-DC flyback The term “flyback” may refer to
Applications for the new product family include chargers for cell phones, cordless phones, digital cameras, PDAs, and MP3/portable audio devices, as well as electronic controls for home appliances and industrial and other auxiliary power supplies.
Design support includes a data sheet, an application note (AN-38), a Reference Design Kit (DAK-73) containing an operational 2.3 W universal input AC-DC power supply and product samples, and the company's power supply design software program, PI Expert(TM).
