AX2596 series are monolithic IC designed for a step down DC/DC converter, and
    own the ability of driving a 3A load without additional transistor. It saves board space. The
    external shutdown funct ion can be controlled by logic level and then come into standby
    mode. The internal compensation makes feedback control having good line and load
    regulation without external design. Regarding protected function, thermal shutdown is to
    prevent over temperatu re operating from damage, and current limit is against over current
    operating of the output switch. If current limit function occurs and V FB is down below 0.5V,
    the switching frequency will be reduced. The AX2596 series operates at a switching
    frequency of 150KHz thus allow smaller sized filter components than what would be
    needed with lower frequency switching regulators. The output version included fixed 5V
    a nd an adjustable type. The chip is available in a 5 Lead TO263 package.
