Performance Data
The previous MuxCapacitor efficiency data was measured using a Tektronix PM3000 power meter.
The figure below shows the test equipment wiring diagram.

Operational Guidelines
It is recommended that the auto-ranging feature of current meters be disabled when performing
efficiency measurements. The MxC 200 over current detector could trip when the current meter
switches from one range to another.
The startup waveform of VIN must be monotonic.
Depending on the startup load and VIN rise time, the startup over current detector could trip. A
high startup load condition plus distributed filter capacitance could cause an over-current
shutdown.
