Test Conditions

When mounted on Allegro demo board with 1332 mm2 (654 mm2 on com-

ponent side and 678 mm2 on opposite side) of 2 oz. copper connected to

the primary leadframe and with thermal vias connecting the copper layers.

Performance is based on current flowing through the primary leadframe and

includes the power consumed by the PCB.
