ACT410

Rev 3, 27-Feb-14

ActivePSR^TMQuasi-Resonant PWM Controller

and overload conditions, it would enter auto restart

mode including cycle-by-cycle current limiting.

FEATURES

• Patented Primary Side Regulation

ACT410 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

ACT410 is idea for application up to 36 Watt.

• 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

• Less than 100mW Standby Power

• Complies with Global Energy Efficiency and

CEC Average Efficiency Standards

• Tiny SOT23-6 Package

APPLICATIONS

• AC/DC Adaptors/Chargers for Smart Phones,

iPADs, ADSL, PDAs, E-books

• Adaptors for Portable Media Player, DSCs,

and Other

GENERAL DESCRIPTION

The ACT410 is a high performance peak current

mode PWM controller which applies ActivePSR^TM

and ActiveQR^TMtechnology. ACT410 achieves

accurate voltage regulation without the need of an

opto-coupler or reference device.

The ACT410 is designed to achieve less than

100mW Standby Power. By applying frequency fold

back and

ActiveQR^TMtechnology, ACT410

exceeds the latest ES2.0 efficiency standard.

ACT410 integrates comprehensive protection. In

case of over temperature, over voltage, short

winding, short current sense resistor, open loop
