... Type ICE3AS02 ICE3BS02 ICE3AS02G ICE3BS02G Version 1.2 ICE3AS02 / ICE3BS02 ICE3AS02G / ICE3BS02G 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 < ...
