The new generation CoolSET™-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.
