    Description

    The ACT50 is a compact, high performance off-line power supply controller that is ideal for use in next generation high performance universal input adapters and chargers. The ACT50 features an advanced 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 Union Blue Angel, and US Energy Star standards.

    The ACT50 is optimized for use in the flyback topology, and requires just a low cost optocoupler and reference device, such as the '431, to provide fully adjustable CC/CV operation.

    This device additionally features a proprietary low EMI driver that can be compatible with both external MOSFET and NPN transistors, and supports emitter-switching to achieve the lowest possible solution cost.

    The ACT50 is available in tiny SOT23-5 or DIP-8 packages.
