ACT512 Datasheet | Active-Semi

ACT512 Rev 4, 13-Feb-14 Active QRTM Quasi-Resonant PWM Controller Features - CCM and Quasi-Resonant Operation - Adjustable up to 75k Hz Switching Frequency - OCP/OLP Protection - Integrated Patented Frequency Foldback Technique - Integrated Patented Line pensation - Built-in Soft-Start Circuit - Line Under-Voltage, Thermal, Output Over- voltage, Output Short Protections - Current Sense Resistor Short Protection - Transformer Winding Short Protection - 100m W Standby Power - plies with Global Energy Efficiency and CEC Average Efficiency Standards - Tiny SOT23-6 Packages ACT512 integrates prehensive protection. In case of over temperature, over voltage, winding short, current sense resistor short, open loop and overload conditions, it would enter into auto restart mode including Cycle-by-Cycle current limiting. ACT512 is to achieve no overshoot and very short rise time even with a big capacitive load with the built-in fast and soft start process. In full...
