5. Burst operation :
In order to minimize power dissipation
in standby mode, the FSDM0565RB enters burst mode
operation. As the load decreases, the feedback voltage
decreases. As shown in Figure 8, the device automatically
enters burst mode when the feedback voltage drops below
V
BURL
(500mV). At this point switching stops and the
output voltages start to drop at a rate dependent on standby
current load. This causes the feedback voltage to rise. Once
it passes V
BURH
(700mV) switching resumes. The feedback
voltage then falls and the process repeats. Burst mode
operation alternately enables and disables switching of the
power Sense FET thereby reducing switching loss in
Standby mode.
