ACT513
Product Brief, 05-Dec-12
ActiveQRTM Quasi-Resonant PWM Controller
ACT513 integrates comprehensive protection. In
case of over temperature, over voltage, short
winding, short current sense resistor, open loop an
d overload conditions, it would enter into auto
restart mode including Cycle-by-Cycle current
limiting.
FEATURES
• CCM and Quasi-Resonant Operation
• Adjustable up to 45kHz Switching Frequency
• OCP/OLP Protection
• Integrated Patented Frequency Foldback
ACT513 is to achieve no overshoot and very short
rise time even with big capacitive load with the built-
in fast and soft start process.
Technique
• Integrated Patented Line Compensation
• Built-in Soft-Start Circuit
In full load condition, ACT513 is able to be
designed to work in both CCM mode and DCM
mode to meet different types of applications. Quasi-
Resonant (QR) operation mode can effectively
improve efficiency during DCM operation, and
reduce the EMI noise and further reduce the
components in input filter.
• Line Under-Voltage, Thermal, Output Over-
voltage, Output Short Protections
• Current Sense Resistor Short Protection
• Transformer Short Winding Protection
• 100mW Standby Power
ACT513 is for application up to 60 Watt.
• Complies with Global Energy Efficiency and

APPLICATIONS
• AC/DC Adaptors/Chargers for Cell Phones,
Cordless Phone, PDAs, E-books
• Adaptors for Portable Media Player, DSCs,
Set-top boxes, DVD players, records
• Linear Adapter Replacements
GENERAL DESCRIPTION
The ACT513 is a high performance peak current
mode PWM controller. ACT513 applies ActiveQRTM
and frequency foldback technique to reduce EMI
and improve efficiency. ACT513’s maximum design
switching frequency is set at 45kHz. Very low
standby power, good dynamic response and
accurate voltage regulation is achieved with an
opto-coupler and the secondary side control circuit.
The burst mode operation enables low standby
power of 100mW with small output voltage ripple.
By applying frequency foldback and ActiveQRTM
technology, ACT513 increases the average system
efficiency compared to conventional solutions and
exceeds the latest ES2.0 efficiency standard with
good margin.
