Elantec Semiconductor Announces Its First Multi-Output, Application-Specific DC:DC Regulators for TFT/LCD Flat Panel Displays.Business Editors MILPITAS, Calif.--(BUSINESS WIRE)--Jan. 30, 2002 -- EL7580C and EL7581C are fully integrated, multiple-output DC:DC voltage regulators, which provide the highest power, best thermal performance and a wide operating range to optimally meet the requirements of large, thin-film transistor (TFT (Thin Film Transistor) The term typically refers to active matrix screens on laptop computers. Active matrix LCD provides a sharper screen display and broader viewing angle than does passive matrix. See LCD and thin film. TFT - Thin Film transistor ) liquid crystal displays liquid crystal display (LCD) Optoelectronic device used in displays for watches, calculators, notebook computers, and other electronic devices. Current passed through specific portions of the liquid crystal solution causes the crystals to align, blocking the passage of light. (LCD) Elantec Semiconductor, Inc. (Nasdaq:ELNT), a leader in high-performance analog integrated circuits Integrated circuits Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1. , today announced two new multi-output, DC:DC Regulator ICs with integrated FET FET: see transistor. (Field Effect Transistor) One of two major categories of transistor; the other is bipolar. FETs use a gate element that, when charged, creates an electromagnetic field that changes the conductivity of a silicon boost regulator, Vcom regulator, and two regulated charge pumps. The new EL7580C and EL7581C are designed for use in 14- to 20-inch-and-larger TFT/LCD monitors, LCD notebook displays, and LCD TVs, as well as portable products such as Pocket PCs and PDAs. The integrated FET boost regulator in both the EL7580C and EL7581C provides the TFT/LCD column driver power, generating +12V at up to 700mA continuous current from a +5V input, with a typical efficiency of 90%. The boost regulator can provide regulated voltages ranging from +5V to +18V. A second linear regulator In electronics, a linear regulator is a voltage regulator based on an active device (such as a bipolar junction transistor, field effect transistor or vacuum tube) operating in its "linear region" (in contrast, a switching regulator is based on a transistor forced to act as an provides the supply for the common plate of the TFT/LCD panel, generating the Vcom voltage ranging from +2V to +13V, with a maximum continuous current of 100mA. A pair of low-power, charge pump, control circuits provides both a regulated positive output voltage between +5V to +40V, and a regulated negative output voltage between -40V to -5V. The positive and negative charge pump voltages provide the TFT/LCD row driver power. The EL7580CL provides all four of these regulated outputs; the EL7581CRE CRE Commercial Real Estate CRE Corporate Real Estate CRE Commission for Racial Equality (Scotland) CRE CCD (Charge Coupled Device) and Readout Electronics CRE Camp Response Element does not include the Vcom amplifier.
