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