Paralleling
The paralleling and current sharing capability of the devices can be demonstrated by
stacking multiple Customer Evaluation Boards and interconnecting the inputs and
outputs with standoffs of sufficient current handling capability to create a 3-dimensional
array. S­­ ee Figure 3 below. When paralleling IBCs the EN control header (J11) should not
be used. The modules should be enabled with the S10 switch. Pre-enabling all modules
before input power is applied does not guarantee a synchronous startup. Therefore, the
load at startup must be sized so that any one module is able to successfully startup into
that load alone.

Input Current Measurement
A current probe can be passed around the +in lead connected to the IBC. Input
capacitors on the Customer Evaluation Board are downstream of this
measurement point.
Efficiency Measurement
As the IBC can deliver and consume large currents, the effect of the PCB must be
considered when making an efficiency measurement. Be certain to accurately measure
the voltage directly at the IBC using the appropriate pair of contact points located at the
corners of the IBC.
