ACT411
ACT411 is Quasi-Resonant PWM Controller manufactured by Active-Semi.
- Part of the ACT411-Active comparator family.
ACT411 Rev 4, 27-Feb-14 Active PSRTM Quasi-Resonant PWM Controller Features - Patented Primary Side Regulation Technology - Quasi-Resonant Operation - Adjustable up to 120k Hz Switching Frequency - +/-5% Output Voltage Regulation - Accurate OCP/OLP Protection - Integrated Output Cord pensation - Integrated Line and Primary Inductance pensation - Built-in Soft-Start Circuit - Line Under-Voltage, Thermal, Output Over- voltage, Output Short Protections - Current Sense Resistor Short Protection - Transformer Short Winding Protection - Less than 100m W Standby Power - plies with Global Energy Efficiency and CEC Average Efficiency Standards - Tiny SOT23-6 Packages and overload conditions, it would enter auto restart mode including cycle-by-cycle current limiting. ACT411 is to achieve no overshoot and very short rise time even with big capacitive load (4000µF) with the built-in fast and soft start process, . The Quasi-Resonant (QR) operation mode can...
