Overview

19-1795; Rev 0; 11/00 Low-Power Triple-Output TFT LCD DC-DC Converter General Description The MAX1779 triple-output DC-DC converter 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 primary high-power DC-DC converter generates a boosted output voltage (VMAIN) up to 13V that is regulated within ±1%.
The low-power BiCMOS control circuitry and the low on-resistance (1Ω) of the integrated power MOSFET allows efficiency up to 91%.
The 250kHz current-mode puls...
