    ■ DESCRIPTIO The LT ®1534/LT1534-1 are a new class of switching regulator designed to reduce conducted and radiated electromagnetic interference (EMI). Ultralow noise and EMI are achieved
    by providing user control of the output switch slew rates.
    Voltage and current slew rates can be independently programmed to optimize switcher harmonic content versus
    efficiency. The LT1534/LT1534-1 can reduce high frequency
    harmonic power by as much as 40dB with only minor losses
    in efficiency.
    The LT1534/LT1534-1 utilize a current mode architecture
    optimized for low noise boost topologies. The ICs include a
    2A power switch along with all necessary oscillator, control
    and protection circuitry. Unique error amp circuitry can
    regulate both positive and negative voltages. The internal
    oscillator may be synchronized to an external clock for more ...
