Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, and in particular relates to a multi-channel voltage converter based on integrated packaging. Background technique [0002] Voltage converters are generally used in military equipment such as ground electronic systems, handheld and interfaces, and are key devices for power supply such as FPGA (Field-Programmable Gate Array) or DSP (Digital Signal Processing, digital signal processing). It has the characteristics of stable output voltage, adjustable output, multi-channel, low dropout voltage, low noise, small size, and simple application, so it is widely used in communication equipment. The stability and low noise of its output voltage directly determine the stability, reliability and safety of FPGA or DSP. [0003] However, the existing voltage converter circuits are usually built with discrete devices, and are generally single-channel devices. This technical implementation meth...
