FSDM0465RB

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

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.
