MAX1748EUE Maxim美信芯片 DC-DC三输出规格手册(V1.0)

MAX1748EUE and MAX8726 are triple-output DC-DC converters designed by Maxim Integrated, specifically for providing regulated voltages needed by active-matrix, thin-film transistor (TFT) liquid-crystal displays (LCDs). These converters come in a low-profile TSSOP package and are capable of converting a 3.3V to 5V input supply voltage into three independent output voltages. The primary 1MHz DC-DC converter in the MAX1748/MAX8726 series is able to generate a boosted output voltage (VMAIN) of up to 13V using ultra-small inductors and ceramic capacitors. This high-power converter is essential for powering the main display components in LCD screens. In addition to the primary converter, there are also two low-power charge pumps included in the design to provide supplementary power to other components in the display system. The use of ceramic capacitors in the design of these converters helps to reduce component size and improve efficiency. This is particularly important in applications where space is limited, such as in portable electronic devices or slim-profile displays. The 1MHz switching frequency of the converter also contributes to its compact design and high efficiency. Overall, the MAX1748EUE and MAX8726 DC-DC converters from Maxim Integrated are ideal for applications requiring multiple regulated voltages for TFT LCD displays. Their compact size, high efficiency, and multiple output options make them a versatile and reliable choice for powering display systems in a variety of electronic devices.
