    LT1683
    Slew Rate Controlled
    Ultralow Noise Push-Pull DC/DC Controller
    DESCRIPTION FEATURES Greatly Reduced Conducted and Radiated EMI
    n Low Switching Harmonic Content
    n Independent Control of Output Switch Voltage and
    Current Slew Rates
    n Greatly Reduced Need for External Filters
    n Dual N-Channel MOSFET Drivers
    n 20kHz to 250kHz Oscillator Frequency
    n Easily Synchronized to External Clock
    n Regulates Positive and Negative Voltages
    n Easier Layout Than with Conventional Switchers The LT В®1683 is a switching regulator controller designed to
    lower conducted and radiated electromagnetic interference
    (EMI). Ultralow noise and EMI are achieved by controlling
    the voltage and current slew rates of external N-channel
    MOSFET switches. Current and voltage slew rates can
    be independently set to optimize harmonic content of
    the switching waveforms vs efficiency. The LT1683 can
    reduce high frequency harmonic power by as much as
    40dB with only minor losses in efficiency.
    The LT1683 utilizes a dual output (push-pull) current
    mode architecture optimized for low noise topologies. ...
