ON Semiconductor Introduces Two New Micro-Packaged DC-DC Converters with Low-Battery Detection.Business Editors/High-Tech Writers PHOENIX--(BUSINESS WIRE)--Oct. 7, 2002 NCP (1) (Network Control Program) See SNA and network control program. (2) (NetWare Core Protocol) The file sharing protocol used in a NetWare network. 1410 and NCP1411 lessen battery drain, reduce board space and simplify power system design in portable and wireless electronics ON Semiconductor (Nasdaq: ONNN) -- globally ranked among the top five suppliers of power management circuits -- today introduced two new high frequency DC-DC DC-DC Direct Current to Direct Current (power conversion) converters with low-battery detectors for use in portable and wireless electronics including PDAs, digital cameras and handheld instruments. The NCP1410 and NCP1411 are micro-powered, monolithic, pulse frequency modulation frequency modulation: see modulation; radio. (1) An earlier magnetic disk encoding method that places clock bits onto the medium along with the data bits. It was superseded by MFM and RLL. (PFM), step-up voltage-switching DC-DC converters. Both devices feature open drain low-battery detectors that help simplify power system design. Configured for use in battery operated handheld electronics with up to 250 milliamps (mA) loading current, these devices deliver adjustable output voltages between 1.5 volts (V) and 5.5V. A synchronous rectifier rectifier, component of an electric circuit used to change alternating current to direct current. Rectifiers are made in various forms, all operating on the principle that current passes through them freely in one direction but only slightly or not at all in the has been integrated into each device -- improving power system efficiency, eliminating the need for external schottky diodes and reducing overall board space. Delivering a high switching frequency of up to 600 kilohertz One thousand cycles per second. See Hertz. (kHz), these converters allow power system designers to use low profile inductor inductor, electric device consisting of one or more turns of wire and typically having two terminals. An inductor is usually connected into a circuit in order to raise the inductance to a desired value. and output capacitors. That helps to reduce board space and cost significantly and also lowers output voltage ripple noise. Both devices include logic-controlled shutdown and 1 amp (A) cycle-by-cycle current limit features.

(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. ), an innovative Ring-Killer feature has been added to the NCP1411. To eliminate the ringing at LX pin that typically occurs when an electronic device working in discontinuous conduction mode, an internal damping switch (M3) has been implemented in the NCP1411. The damping switch (M3) provides a low impedance path to dissipate the residual energy that was stored in the inductor during switch-off period of the discontinuous conduction mode. As a result, the unwanted ringing and EMI created by the capacitance and inductance at the LX node are eliminated. Bringing high performance with all these features, the NCP1410 and NCP1411 DC-DC converters deliver an impressive power efficiency of 92 percent and a low quiescent supply current of 9 uA. As such, they assist in further extending the battery life so critical to designers and manufacturers of leading-edge portable and wireless electronics. Packaging and Price Both the NCP1410 and NCP1411 are offered in the space-saving 3 mm x 5 mm Micro-8 package. The NCP1410 is priced at $0.85 per unit in 10,000 unit quantities. The NCP1411 is $1.00 per unit in 10,000 unit quantities.
