TFT-LCD regulator offers a cool way out

Milpitas, Calif. – Touting extremely high efficiency and thus cooler system operation, the EL7585A quad-output regulator from Intersil provides a highly integrated power source for large (19 inches and greater) thin-film-transistor liquid-crystal displays (TFT-LCDs) of the kind used in TVs and desktop monitors. Its so-called boost supply boasts the industry’s largest integrated field-effect transistor for this application, providing up to 3.5 amps.
