NOTES:
1. Unless otherwise noted, C
i
= 100 nF and R
i
= 150 k. 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:
R
L
= 8 means Load = 15 H + 8 + 15 H
R
L
= 4 means Load = 15 H + 4 + 15 H
Very low DCR 15 H inductors (50 m) have been used for the following graphs. Thus, the electrical load
measurements are performed on the resistor (8 or 4 ) in differential mode.
3. For Efficiency measurements, the optional 30 kHz filter is used. An RC low−pass filter is selected with
(100 , 47 nF) on each PWM output.
