SLOW DECAY MODE
Figure 11 shows the operation of the bridge in the Slow Decay mode. At the start of the off time, the lower power
MOS is switched off and the current recirculates around the upper half of the bridge. Since the voltage across
the coil is low, the current decays slowly. After the dead time the upper power MOS is operated in the synchro-
nous rectification mode. When the monostable times out, the lower power MOS is turned on again after some
delay set by the dead time to prevent cross conduction.
