5. Burst Operation:
To minimize power dissipation in
standby mode, the FSDM0465RB 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 the
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 SenseFET thereby reducing
switching loss in Standby mode.
