    High-Voltage, High-Speed Telecom DC-to-DC Controller General Description Features The MIC9130 is a current-mode PWM controller that efficiently
    converts –48V telecom voltages to logic levels. The MIC9130
    features a high voltage start-up circuit that allows the device to
    be connected to input voltages as high as 180V. The high input
    voltage capability protects the MIC9130 from line transients
    that are common in telecom systems. The start-up circuitry
    also saves valuable board space and simplifies designs by
    integrating several external components.
    The MIC9130 is capable of high speed operation. Typically
    the MIC9130 can control a sub-25ns pulse width on the gate
    out pin. Its internal oscillator can operate over 2.5MHz, with
    even higher frequencies available through synchronisation.
    The high speed operation of the MIC9130 is made safe by
    the very fast, 34ns response from current sense to output,
    minimizing power dissipation in a fault condition.
    The MIC9130 allows for the designs of high efficiency power
    supplies. It can achieve efficiencies over 90% at high output
    currents. Its low 1.3mA quiescent current allows high efficiency
    even at light loads.
    The MIC9130 has a maximum duty cycle of 50%. For designs requiring a high duty cycle, refer to the MIC9131. The
    MIC9130 is available in a 16-pin SOP and 16-pin QSOP
    package options. The rated junction temperature range is ...
