Mode to reach the lowest Standby Power Requirements
• Active Burst Mode for lowest Standby Power
<100mW at no load. As the controller is always active
@ light load controlled by Feedback signal
during Active Burst Mode, there is an immediate response
• Fast load jump response in Active Burst Mode on load jumps without any black out in the SMPS. In Active
