Product Summary

The MAX1748EUE is a triple-output DC-DC converter in a low-profile TSSOP package. The MAX1748EUE can 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.
