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