Description
The F3 Controller provides Active Burst Mode to reach the
lowest Standby Power Requirements <100mW at no load.
As during Active Burst Mode the controller is always active
there is an immediate response on load jumps possible
without any black out in the SMPS. In Active Burst Mode
the ripple of the output voltage can be reduced <1%.
Furthermore Latched Off Mode is entered in case of
Overtemperature, Overvoltage or Short Winding. If
Latched Off Mode is entered only the disconnection from
the main line can reset the Controller. Auto Restart Mode
is entered in case of failure modes like open loop or
overload. By means of the internal precise peak current
limitation the dimension of the transformer and the
secondary diode can be lower which leads to more cost
efficiency. An adjustable blanking window prevents the IC
from entering Auto Restart Mode or Active Burst Mode in
case of high Load Jumps.
