The invention provides a multi-channel
voltage converter based on integral packaging. The multi-channel
voltage converter comprises a plurality of mutually independent
voltage conversion units packaged inside an integral shell; each voltage conversion unit comprises a voltage conversion unpacked
chip, the input end of each voltage conversion unpacked
chip is grounded through a corresponding firstcapacitor, the output end of each voltage conversion unpacked
chip is grounded through a corresponding second
capacitor and is connected to an output voltage adjusting end of the voltage conversion unpacked chip through a corresponding
resistor, the output voltage adjusting end of each voltage conversion unpacked chip is externally connected to an adjustable
resistor, the output voltage of each voltage conversion unpacked chip is adjusted by adjusting the resistance value of the corresponding adjustable
resistor, and pins correspondingly connected with the input end, output end, output voltageadjusting end and enabled end of each voltage conversion unpacked chip are led out from one side of the integral shell. According to the multi-channel
voltage converter, the multi-channel integrationof the power device is realized by using the integral packaging, so that the size of circuit packaging is reduced, the heat dissipation effect is preferable, and the
operating temperature range is wide.
