  • 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 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.
