ACT330 Active-Semi High Performance ActivePSRTM Primary Switching Regulator and US Energy Star standards) while using very few external components. FEATURES  Ultra Low Standby Power < 30mW 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.  Meet 5-Star Energy Saving Requirement  Patented Primary Side Regulation Technology  No Opto-Coupler 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.  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 The ACT330 is optimized for 2W to 7W applications. It is available in space-saving 6 pin SOT23-6 package.  Complies with all Global Energy Efficiency and CEC Average Efficiency Standards Figure 1: Simplified Application Circuit  Adjustable power from 2W to 7W  Minimum External Components  Tiny SOT23-6 Package INPUT OUTPUT APPLICATIONS  Chargers for Cell Phones, PDAs, MP3, Portable Media Players, DSCs, and Other Portable Devices and Appliances  RCC Adapter Replacements VDD  Linear Adapter Replacements BD ACT330  Standby and Auxiliary Supplies SW CS GENERAL DESCRIPTION FB G The ACT330 belongs to the high performance patented ActivePSRTM Family of Universal-input AC/DC off-line controllers for battery charger and adapter applications. It is designed for flyback topology working in discontinuous conduction mode (DCM). The ACT330 meets all of the global energy efficiency regulations (CEC, European Blue Angel, Innovative PowerTM -1- Active-Semi Confidential¯Do Not Copy or Distribute ActivePSRTM is a trademark of Active-Semi.
