7) Use the following formulas to calculate the efficiency:

Efficiency= (Pout/Pin) × 100(%)

Pin = Iin × Vin

Pout = Iout × Vout

For IPM12C series

The following graph shows the efficiency results of the IPM12C0A0R04A converter measured at

different operating points, the output voltage was set at 5V.
