MAX1748EUE - Brand New Maxim Integrated Special Purpose Voltage Regulators
-
Description
The MAX1748EUE is a triple-output DC-DC converter in a low-profile TSSOP package, designed to provide regulated voltages for active-matrix, thin-film transistor (TFT) liquid-crystal displays (LCDs). It consists of one high-power DC-DC converter and two low-power charge pumps, converting the input supply voltage into three independent output voltages. The primary boost regulator in this converter operates at 1MHz and can generate a boosted output voltage (VMAIN) up to 13V. With its high efficiency of up to 93% and compact design, it is an ideal choice for applications requiring multiple regulated voltages.
