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.
