Product Brief, 15-Apr-11
High Performance ActivePSRTM Primary Switching Regulator
The ACT365 ActivePSRTM is optimized for high
performance, cost-sensitive applications, and
FEATURES
• Patented Primary Side Regulation
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 ACT365 achieves excellent
regulation and transient response, yet requires less
than 150mW of standby power.
Technology
• No Opto-Coupler
• Suitable Operation Frequency up to 85kHZ
• Best-in-Class Constant Voltage Accuracy
• Proprietary Fast Startup with Big Capacitive
Load
• Built-in Soft-Start Circuit
• Integrated Line and Primary Inductance
Compensation
The ACT365 is optimized for compact size 6W to
12W adapter applications. It is available in SOP-8
package.
• 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
• Dedicate Adapter Application from 6W to
12W
APPLICATIONS
• RCC Adapter Replacements
• Linear Adapter Replacements
• Standby and Auxiliary Supplies
GENERAL DESCRIPTION
The ACT365 belongs to the high performance
patented ActivePSRTM Family of Universal-input
AC/DC off-line controllers for adapter applications.
It is designed for flyback topology working in
discontinuous conduction mode (DCM). The
ACT365 meets all of the global energy efficiency
regulations (CEC, European Blue Angel, and US
Energy Star standards) while using very few
external components.

Power Supply. This pin provides bias power for the IC during startup and steady state operation.
Feedback Pin. Connect this pin to a resistor divider network from the auxiliary winding.
Current Sense Pin. Connect an external resistor (RCS) between this pin and ground to set peak
current limit for the primary switch. The peak current limit is set by (0.396V × 0.9) / RCS. For more
detailed information, see Application Information.
