Abstract

Examples of the present invention disclose a DC / DC test system and method.In this scheme, the test system composed of testing host, main control unit, DC / DC unit, programmable power supply, input monitoring unit, output monitoring unit, and load unit can automatically test the efficiency test of the DC / DC unit.The test of linear adjustment and load adjustment rates improved test efficiency.

Description

technical field [0001] The invention relates to the technical field of signal testing, in particular to a DC / DC testing system and method. Background technique [0002] DC-to-DC power supply (Direct Current / Direct Current, DC / DC) can convert the input DC power into the required DC power. For example, in an AMOLED display, it is necessary to convert the input DC voltage into AVDD, ELVDD, ELVSS three DC output voltage. There is an important test for AMOLED DC / DC: power efficiency test. The traditional power efficiency test scheme is: use multimeters and oscilloscopes to test DC / DC input, output voltage and current parameters under different input voltages, output voltages, and different loading conditions. However, since each parameter is required to be tested at the same time, multiple devices need to be used at the same time, and the process of obtaining test data from many devices is also very time-consuming, resulting in a cumbersome power efficiency test process. Cont...
