Scheme Provides High Side Current Sensing for White LED Drivers:  02/19/04 EDN Design Ideas  /  (added 1/05)  White LEDs find wide use in backlighting color-LCD screens in most portable devices, such as cellular phones, PDAs, and MP3 players. Multiple LEDs often connect in series to ensure that the same current flows through every LED. To forward-bias these LEDs, a voltage of 10 to 16V comes from an inductor-based boost regulator, such as an SP6690....

Simple Active-Matrix-LCD Bias Supply Operates from Battery Input :  02/03/00 EDN EDN Design Ideas. /  (added 11/05)  Many active-matrix-LCD applications need multiple voltages for thin-film-transistor (TFT) bias. Typically, three voltages are necessary: 5V for the column driver; a positive voltage, such as 10V; and a negative voltage, such -5V, for the TFT gate drive, or row driver. For handheld electronic devices, a battery....
