Performance test board for device under test, has DC-DC converter with input terminal to which internal supply sources of test system are connected and output terminal to which power terminal of device under test are connected

摘要

The test board has a DC-DC converter (5) with an input terminal to which multiple internal power supply sources of a test system are connected in parallel. A power supply terminal of the device under test (DUT) is connected an output terminal. An internal power supply source of the test system is connected to a control terminal. A transistor includes a terminal that is connected to the input terminal of the converter.
