Description
P DSO 8 3 6
• Active Burst Mode for lowest Standby Power
The F3 Controller provides Active Burst Mode to reach the
@ light load controlled by Feedback Signal
lowest Standby Power Requirements <100mW at no load.
• Fast load jump response in Active Burst Mode As the controller is always active during Active Burst
• 500V Startup Cell switched off after Start Up
Mode, there is an immediate response on load jumps
• 100/67kHz internally fixed switching frequency without any black out in the SMPS. In Active Burst Mode
• Auto Restart Mode for Overtemperature Detection the ripple of the output voltage can be reduced <1%.
• Auto Restart Mode for VCC Overvoltage Detection Furthermore, to increase the robustness and safety of the
• Auto Restart Mode for Overload and Open Loop system, the device enters into Auto Restart Mode in the
• Auto Restart Mode for VCC Undervoltage
cases of Overtemperature, VCC Overvoltage, Output
• Blanking Window for short duration high current Open Loop or Overload and VCC Undervoltage. By
• User defined Soft Start
means of the internal precise peak current limitation, the
• Minimum of external components required
dimension of the transformer and the secondary diode can
• Max Duty Cycle 72%
be lowered which leads to more cost efficiency. An
• Overall tolerance of Current Limiting < ±5%
adjustable blanking window prevents the IC from entering
• Internal PWM Leading Edge Blanking
Auto Restart Mode or Active Burst Mode unintentionally in
• Soft switching for low EMI
case of high load jumps.
