MA5609-38V Synchronous Buck Converter With CC/CV DataSheet

GENERAL DESCRIPTION
    MA5609 is a wide input voltage, high efficiency Active CC step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. MA5609 provides up to 4A output current at 160kHz switching frequency. Current mode control provides fast transient response and cycle-by-cycle current limit.
    An internal soft-start prevents inrush current at turn-on, This device, available in an SOP8L-EP(Exposed pad) package, provides a very compact solution with minimal external components.
