Figure 9. Conduction time sensing during normal operation
Once in sleep mode, gate driving is re-enabled when body diode conduction time of both
MOSFETs exceeds 60 % of the half-cycle. Figure 10 shows details of time measuring for
sleep mode exiting.
Figure 10. Conduction time sensing under sleep mode
Also in this case the decision is made considering the measurement on eight consecutive
switching cycles.
Furthermore, after each sleep mode entering/exiting transition, the timing is ignored for a
certain number of cycles, to let the resulting transient in the output current fade out; then the
