    Step-Down Switching
    Regulator
    ponents, are included on the chip. The topology is a classic
    positive “buck” configuration but several design innovations allow this device to be used as a positive-to-negative
    converter, a negative boost converter, and as a flyback
    converter. The switch output is specified to swing 40V
    below ground, allowing the LT1074 to drive a tappedinductor in the buck mode with output currents up to 10A. FEATURES
