ON Semiconductor Introduces Tiny 3 MHz Synchronous Step-Down DC-DC Converter for Portable and Consumer Applications.The NCP (1) (Network Control Program) See SNA and network control program. (2) (NetWare Core Protocol) The file sharing protocol used in a NetWare network. 1523 and NCP1523B Deliver up to 93 Percent Efficiency and Reduce Overall Solution Size with Built-in 3 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. Switching Frequency Feature and Ultra-small 2.1 x 1.1 x 0.6 mm Package PHOENIX -- ON Semiconductor (Nasdaq: ONNN), a leading global supplier of efficient power management solutions, today introduced two new high-performing pulse width modulation See PWM. (PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a ), 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 It was superseded by MFM and RLL.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) and PWM-only dc-dc converters optimized for portable applications. Supplying clean output voltage with very low ripple voltage Ripple voltage The time-varying part of a voltage that is ideally time-invariant. Most electronic systems require a direct-current voltage for at least part of their operation. and fast transient response, the new NCP1523 and NCP1523B are ideal for use in power sensitive applications such as micro hard disk drives found in multimedia portable devices. The NCP1523 and NCP1523B feature a high switching frequency of 3 megahertz One million cycles per second. See MHz. MegaHertz - (MHz) Millions of cycles per second. The unit of frequency used to measure the clock rate of modern digital logic, including microprocessors. (MHz), which enables the use of a smaller 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. down to 1 micro Henry. The devices deliver high power efficiency - up to 93 percent - thanks to synchronous rectification to extend battery life and reduce external part count. To supply power to even the most demanding microprocessor in portable electronics, these new dc-dc converters provide very fast response times. The NCP1523 features automatic switching PWM/PFM modes, which improve system efficiency at a light load. The PWM-only mode, featured in the NCP1523B, offers an efficient load transient solution and low output voltage ripple. Additionally, these new devices offer integrated soft-start, cycle-by-cycle current limiting and thermal shutdown protection. "These new converters address critical performance and size demands for our portable electronics customers," said Hyung-Sup Kim, marketing director of ON Semiconductor's Digital Consumer Products Group. "Not only do these NCP1523 devices meet the most stringent power requirements for portable electronics, they provide superior efficiency performance in one of the smallest packages currently offered in the market." Available in an adjustable output voltage from 0.9 V to 3.3 V, the NCP1523 and NCP1523B are packaged in the tiny 2.1 mm x 1.1 mm 8-pin Flip-Chip. They are priced at $0.75 per unit in 1,000-unit quantities. For additional technical information visit www.onsemi.com, or contact Crystal Lam at crystal.lam@onsemi.com.
