- Operation principle
Fig. 6 Operation waveforms of CH1, CH2 and CH3 drive parts
voltage of the filter output (RCIN) increases with the internal time constant of 2.4usec (time constant =
R*C=24 pF * 100 Kohm =2.4usec). Then the output current of V-I converter is given by
The output voltages of power amplifiers are, then, given as:
If FWD is high and REV is low, then SW_FWD and SW_REV become on and off, respectively.
This causes the internal capacitor to be charged with sourcing current of 22 uA and consequently the
