Abstract

The invention relates to an adjustable power supply of an integrated circuit test board and the integrated circuit test board. The adjustable power supply of the integrated circuit test board comprises a controller and at least two power supply modules, wherein the at least two power supply modules are connected in series on an output end of the controller in a daisy chain topological structure, the power supply module comprises an adjusting assembly, a first DCDC power supply and a second DCDC power supply, an input end of the adjusting assembly is electrically connected with the output end of the controller, a first output end of the adjusting assembly is electrically connected with the feedback input end of the first DCDC power supply, a second output end of the adjusting assembly is electrically connected with the feedback input end of the second DCDC power supply, the adjusting assembly is used for adjusting the output voltage of the first DCDC power supply and the output voltageof the second DCDC power supply according to the control signals outputted by the controller. According to the adjustable power supply, a problem that the output of the power supply voltage of the integrated circuit test board is unstable in the prior art is solved, and the technical effect of ensuring the stable output of the adjustable power supply voltage of the integrated circuit test board isrealized.

Description

technical field [0001] The embodiment of the present application relates to the technical field of integrated circuits, in particular to an adjustable power supply of an integrated circuit test board and the integrated circuit test board. Background technique [0002] Integrated Circuit (Integrated Circuit, referred to as IC); as the name implies, it is a certain number of commonly used electronic components, such as resistors, capacitors, transistors, etc. circuit. [0003] After the integrated circuit design is completed, it needs to be tested for its function and electrical characteristics. The test content includes the functional test (Functional Test, referred to as FT) and electrical characteristic test (Circuit Probing, referred to as CP) of the entire integrated circuit chip, as well as integrated circuit testing. Reliability test of whether the current, voltage, and frequency of the chip are stable in a high-temperature environment. At present, the integrated circ...
