TYPICAL APPLICATION CONT’D  
VFB Sampling Waveforms  
ACT361 senses the output voltage information  
through the VFB waveforms. Proper VFB waveforms  
are required for IC to operate in a stable status. To  
avoid mis-sampling, 1.38µs blanking time is added  
to blank the ringing period due to the leakage  
inductance and the circuit parasitic capacitance.  
Figure 2 is the recommended VFB waveform to  
guarantee the correct sampling point so that the  
output information can be sent back into the IC to  
do the appropriate control.
