ICE3B0565J

Product Summary

The ICE3B0565J is an Off-Line SMPS Current Mode Controller with integrated 650V Startup Cell/Depletion CoolMOS. The ICE3B0565J meets the requirements for Off-Line Battery Adapters and low cost SMPS for the lower power range. By use of a BiCMOS technology a wide VCC range up to 26V is provided. The ICE3B0565J covers the changes in the auxiliary supply voltage if a CV/CC regulation is implemented on the secondary side. Furthermore an Active Burst Mode is integrated to fullfill the lowest Standby Power Requirements <100mW at no load and Vin = 270VAC. 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%.
