Description
The new generation CoolSET™-F3 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 Overtemperature, VCC Overvoltage, Output
Open Loop or Overload and VCC Undervoltage. 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 or Active Burst Mode unintentionally during
high load jumps. The CoolSET™-F3 family consists a wide
power class range of products for various applications.
Product Highlights

Requirements < 100mW
• Protection features (Auto Restart Mode) to increase
robustness and safety of the system
• Adjustable Blanking Window for high load jumps to
increase system reliability
• Isolated drain package for TO220/I2PAK
• Increased creepage distance for TO220/I2PAK
• Wide power class of products for various applications
