Description: The ACT34 belongs to the high performance ActiveSwitcherTM<...
The ACT34 belongs to the high performance ActiveSwitcherTM family of universal input AC off-line controllers for adapter and battery-charger applications. The ACT34 was optimized for costsensitive applications, and utilizes Active-Semi's patent-pending primary-side feedback to provide accurate, programmable CV/CC operation without the need of an optocoupler or a reference device such as the '431.
The ACT34 utilizes an advanced, proprietary current-mode PWM control architecture that achieves the smallest form-factor and fast transient response yet requires less than 300mW of standby power, surpassing even the latest requirements of the California Energy Commission (CEC), the European Blue Angel, and the US Energy Star Standards.
Additional features include over power protection, and foldback short circuit current limit. The ACT34 is available in a tiny SOT23-6 package.
