Overview
ACT410 Rev 3, 27-Feb-14 ActivePSRTM Quasi-Resonant PWM Controller FEATURES • Patented Primary Side Regulation Technology • Quasi-Resonant Operation • Adjustable up to 120kHz Switching Frequency • +/-5% Output Voltage Regulation • Accurate OCP/OLP Protection • Integrated Output Cord Compensation • Integrated Line and Primary Inductance Compensation • 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 100mW Standby Power • Complies with Global Energy Efficiency and CEC Average Efficiency Standards • Tiny SOT23-6 Package and overload conditions, it would enter auto restart mode including cycle-by-cycle current limiting.
ACT410 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 effect...
