ActivePSRTM Quasi-Resonant PWM Controller
FEATURES
• Patented Primary Side Regulation
Technology
• Quasi-Resonant Operation
• Adjustable up to 85kHz Switching Frequency
• +/-5% Output Voltage Regulation
• Accurate OCP/OLP Protection
• Integrated Output Cord Compensation
• 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
• Less than 100mW Standby Power
• Complies with Global Energy Efficiency and
CEC Average Efficiency Standards
• Tiny SOT23-6 Packages
mode including cycle-by-cycle current limiting.
ACT413 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, .
The Quasi-Resonant (QR) operation mode can
effectively improve efficiency, reduce the EMI noise
and further reduce the components in input filter.
ACT413 is idea for application up to 36 Watt.

Simplified Application Circuit
APPLICATIONS
• AC/DC Adaptors/Chargers for Smart Phones,
iPADs, ADSL, PDAs, E-books
• Adaptors for Portable Media Player, DSCs,
and Other
GENERAL DESCRIPTION
The ACT413 is a high performance peak current
mode PWM controller which applies ActivePSRTM
and ActiveQRTM technology. ACT413 achieves
accurate voltage regulation without the need of an
opto-coupler or reference device.
The ACT413 is designed to achieve less than
100mW Standby Power. By applying frequency fold
back and ActiveQRTM technology, ACT413
exceeds the latest ES2.0 efficiency standard.
ACT413 integrates comprehensive protection. In
case of over temperature, over voltage, short
winding, short current sense resistor, open loop
and overload conditions, it would enter auto restart
