Product Summary
The MAX1779EUE+T is a triple-output DC-DC converter. It provides highly efficient regulated voltages required by small active matrix, thin-film transistor (TFT) liquid-crystal displays (LCDs). One high-power DC-DC converter and two low-power charge pumps convert the +2.7V to +5.5V input supply voltage into three independent output voltages. The applications of the MAX1779EUE+T are TFT Active-Matrix LCD Displays, Passive-Matrix LCD Displays, PDAs, Digital-Still Cameras and Camcorders.
