Features
Description
• 650V avalanche rugged CoolMOS™ with built in The new generation CoolSET™-F3 provides Active Burst
switchable Startup Cell
• Active Burst Mode for lowest Standby Power
@ light load controlled by Feedback signal
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
• Fast load jump response in Active Burst Mode on load jumps without any black out in the SMPS. In Active
• 67/100 kHz fixed switching frequency
Burst Mode the ripple of the output voltage can be reduced
• Auto Restart Mode for Overtemperature Detection <1%. Furthermore, to increase the robustness and safety
• Auto Restart Mode for Overvoltage Detection
• Auto Restart Mode for Overload and Open Loop
• Auto Restart Mode for VCC Undervoltage
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
• Blanking Window for short duration high current
• User defined Soft Start
• Minimum of external components required
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
• Max Duty Cycle 72%
• Overall tolerance of Current Limiting < ±5%
• Internal PWM Leading Edge Blanking
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
• Soft driving for low EMI
power class range of products for various applications.
