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 Auto
Restart Mode in the cases of Overtemperature, VCC
Overvoltage, Output Open Loop or Overload and VCC
Undervoltage. By means of the 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.
