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 <1%. Furthermore, to increase the robustness and safety of the system, the device enters into Auto Restart Mode in the cases of Over temperature, VCC Over voltage, Output Open Loop or Overload and VCC Under voltage. By means of the internal precise peak current limitation, the dimension of the transformer and the secondary diode can be lowered which leads to more cost efficiency. An adjustable blanking window prevents the IC from entering Auto Restart Mode or Active Burst Mode unintentionally in case of high load jumps.

Product Usage
The ICE3BS02G is a highly integrated stand-alone primary PWM (Pulse Width Modulation) controller in a DIP-8 package, designed for fixed frequency flyback converters. It's commonly used in various power conversion circuits to manage energy efficiency and provide power regulation in applications, including:
AC/DC Power Adapters: Used in power supplies for laptops, smartphones, tablets, and other consumer electronic devices to convert AC mains power to the required DC voltage.
Standby Power Supplies: Employed in low standby power applications such as television and monitor standby circuits to ensure minimal power consumption when the device is not in active use.
Battery Chargers: Utilized in chargers for lithium-ion batteries, NiMH batteries, and other rechargeable batteries to provide regulated charging currents and protect the batteries from overcharging.
Auxiliary Power Supplies: Found in appliances such as refrigerators, microwave ovens, and air conditioners to provide auxiliary power for control electronics and other internal circuits.
Network and Telecommunication Equipment: Used in power supplies for routers, modems, and other networking equipment to deliver consistent power while managing efficiency and thermal performance.
The ICE3BS02G features include various protection mechanisms such as overload protection, overvoltage protection, and built-in frequency jitter for EMI reduction, making it suitable for applications requiring high reliability and safety standards.
