| AXC-102 ACTIVE FILTER FOR RIPPLE ATTENUATION 20A PRELIMINARY Features : ? ? ? ? ? ? ? ? ? High Efficiency. Superior Performance at Low Frequencies. Output Impedance Less Than 5m. Retriggerable / Non-retriggerable Circuit Breaker. Shut Down. Sense Input Control. Status Output. Wide Operation Range 0-28V. Programmable Voltage Drop. ? Compact Size. Product Description The AXC-102 is a power filter which provide high attenuation starting at extremely low frequencies (30dB@20Hz). The device is designed for positive supply of 0 to 28 Volts and up to 20Amp load. The output voltage tracks the DC input voltage with 0.6V drop (adjustable). Full performance is kept for input ripple of up to 0.8 Volts p-p. Exceptional effort has been made to maintain low output impedance (less than 5m at audio frequencies). The AXC filters are designed to meet the most stringent noise requirements in electronic equipment, laboratory power supplies, audio equipment, etc. Sense input provides a constant DC voltage drop across the AXC102. A programmable current circuit breaker shuts down the device when the current trough the module exceeds the rated current (programmable). The circuit breaker has two modes of operation: Retriggerable and Non-retriggerable mode. A CBS (Circuit Breaker Status) indicates when the device is in disconnected mode. A low level voltage (less than 1V), at SD (Shut Down) input, shuts down the output voltage and the quiescent current drops below 2.5mA. This feature fits power management, as well as battery power saving applications. Applications ? ? ? ? ? Laboratory Power Supply. Mixed Signal Power Splitter. Automotive Power Filter. Professional Audio Systems. Power Management.
