NOTES:
1. Unless otherwise noted, Ci = 100 nF and Ri= 150 kW. Thus, the gain setting is 2 V/V and the cutoff frequency of the
input high pass filter is set to 10 Hz. Input capacitors are shorted for CMRR measurements.
2. To closely reproduce a real application case, all measurements are performed using the following loads:
RL = 8 W means Load = 15 mH + 8 W + 15 mH
RL = 4 W means Load = 15 mH + 4 W + 15 mH
Very low DCR 15
mH inductors (50 mW) have been used for the following graphs. Thus, the electrical load
measurements are performed on the resistor (8
W or 4 W) in differential mode.
3. For Efficiency measurements, the optional 30 kHz filter is used. An RC low−pass filter is selected with
(100
W, 47 nF) on each PWM output.
