Description
The new generation CoolSET -F3 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 or Active Burst Mode unintentionally during high load jumps. The CoolSET
-F3 family consists a wide power class range of products for various applications.
