More Information
Summary:The utility model provides a single interface display mainboard based on NT68150, include: power source VIN, DCDC voltage conversion module, scaler control chip module, VGA show input interface module, liquid crystal display module and press the key panel module. Power source VIN meets outside DC power supply, constitutes power supply circuit with the DCDC voltage conversion module, for the power supply of whole circuit. Scaler control chip module includes the MCU chip, the integrated LDO chip of MCU chip, and a LDO chip links to each other with integrated the 2nd LDO chip in the DCDC voltage conversion module. The utility model relates to a there are a LDO chip and a LDO chip, simplified the circuit structure of display mainboard, the design has single interface, and it is great to be particularly useful for purchase quantity, the lower occasion of performance requirement, and the low price, the price / performance ratio is higher, can effectively reduce the operating cost of enterprise, practices thrift soc
