Triple-Output TFT-LCD DC-DC Converters
General Description
The MAX1748/MAX8726 triple-output DC-DC converters in a low-profile TSSOP package provide the regulated voltages required by active-matrix, thin-film
transistor (TFT) liquid-crystal displays (LCDs).
One high-power DC-DC converter and two low-power charge pumps convert the +3.
3V to +5V input supply voltage into three independent output voltages.
The primary 1MHz DC-DC converter generates a boosted output voltage (VMAIN) up to 13V using ultra-small inductors and ceramic capacitors.
The low-power BiCMOS control circuitry and the low on-resistance (0.
35Ω) of the integrated p...
