Abstract: A communication interface buffer comprises: a data bus connection adapted to be coupled to a bus interface contact; and a ground. The communication interface buffer also comprises an output transistor with a first current terminal, a second current terminal and a control terminal, the first current terminal coupled to the data bus connection, the second current terminal coupled to ground, and the control terminal adapted to receive a drive signal. The communication interface buffer also comprises a control circuit coupled to the control terminal of the output transistor, wherein the control circuit is configured to: turn off the output transistor during a first interval that starts when the data bus connection is coupled to the bus interface contact; and turn on the output transistor after the first interval is complete.

Abstract: A system includes a switching converter, an input voltage source coupled to an input of the switching converter, and a load coupled to an output of the switching converter. The system also includes a load sense circuit coupled to the load and configured to provide a load sense signal. The system also includes an oscillator coupled to the switching converter and configured to provide a spread spectrum modulated (SSM) clock signal to the switching converter, wherein a frequency of the SSM clock signal varies as a function of the load sense signal.

Abstract: A system includes a controller for automated test equipment (ATE) contactor to interface with a device under test (DUT) including a power converter having a primary and secondary side, each side has an input/output (I/O) pin. The controller causes the ATE contactor to apply a load current on the secondary side of the power converter at a first value and vary the load current to a second value. The contactor receives first and second indications, at the first and second load currents, of a voltage on the primary side I/O pin, a voltage on the primary side of the power converter, an input current on the primary side of the power converter, a voltage on the secondary side I/O pin, and a voltage on the secondary side of the power converter. The controller determines a primary and secondary side ATE contactor resistances based on the first and second indications.
