ACT41X  
Product Brief, 06-Dec-12  
ActivePSRTM Quasi-Resonant PWM Controller  
and overload conditions, it would enter auto restart  
mode including cycle-by-cycle current limiting.  
FEATURES  
• Patented Primary Side Regulation  
ACT41X 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, .  
Technology  
• Quasi-Resonant Operation  
• Adjustable up to 120kHz Switching  
The Quasi-Resonant (QR) operation mode can  
effectively improve efficiency, reduce the EMI noise  
and further reduce the components in input filter.  
Frequency  
• +/-5% Output Voltage Regulation  
• Accurate OCP/OLP Protection  
ACT41X is idea for application up to 36 Watt.  
Figure 1:  
• Integrated Output Cord Compensation  
Simplified Application Circuit  
• 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  
• 100mW Standby Power  
• Complies with Global Energy Efficiency and  
CEC Average Efficiency Standards  
• Tiny SOT23-6 Packages  
APPLICATIONS  
• AC/DC Adaptors/Chargers for Cell Phones,  
ADSL, PDAs, E-books  
• Adaptors for Portable Media Player, DSCs,  
and Other  
GENERAL DESCRIPTION  
The ACT41X is a high performance peak current  
mode PWM controller which applies ActivePSRTM  
and ActiveQRTM technology. ACT41X achieves  
accurate voltage regulation without the need of an  
opto-coupler or reference device.  
The ACT41X is designed to achieve less than  
100mW Standby Power. By applying frequency fold  
back and  
ActiveQRTM technology, ACT41X  
exceeds the latest ES2.0 efficiency standard.  
ACT41X integrates comprehensive protection. In  
case of over temperature, over voltage, short  
winding, short current sense resistor, open loop
