Active-Semi ACT330 High Performance ActivePSRTM Primary Switching Regulator • Ultra Low Standby Power < 30mW • Meet 5-Star Energy Saving Requirement • Patented Primary Side Regulation Technology • No Opto-Coupler • Best-in-Class Constant Voltage, Constant Current Accuracy • Low EMI • Proprietary Fast Startup Circuit • Built-in Soft-Start Circuit • Integrated Line and Primary Inductance Compensation • Integrated Programmable Output Cord Resistance Compensation • Line Under-Voltage, Output Over-Voltage, Output Short-Circuit and Over-Temperature Protection • Complies with all Global Energy Efficiency and CEC Average Efficiency Standards • Adjustable power from 2W to 7W • Minimum External Components • Tiny SOT23-6 Package and US Energy Star standards while using very few external components. The ACT330 ensures safe operation with complete protection against all fault conditions. Built-in protection circuitry is provided for output shortcircuit, output over-voltage, line under-voltage, and over temperature conditions. The ACT330 ActivePSRTM is optimized for high performance, cost-sensitive applications, and utilizes Active-Semi’s proprietary primary-side feedback architecture to provide accurate constant voltage, constant current CV/CC regulation without the need of an opto-coupler or reference device. Integrated line and primary inductance compensation circuitry provides accurate constant current operation despite wide variations in line voltage and primary inductance. Integrated output cord resistance compensation further enhances output accuracy. The ACT330 achieves excellent regulation and transient response, yet requires less than 30mW of standby power. The ACT330 is optimized for 2W to 7W applications. It is available in space-saving 6 pin SOT23-6 package.
