... ICE3DS01/G Type Ordering Code ICE3DS01L ES Samples available ICE3DS01LG Q67040-S4549-A102 Version 2.0 Description 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 < ...
