    Wide Input Voltage, Synchronous Buck
    Controllers Featuring Adaptive On-Time
    Control
    Hyper Speed Control™ Family General Description Features The Micrel MIC2176-1/-2/-3 is a family of constant-frequency,
    synchronous buck controllers featuring a unique digitally
    modified adaptive ON-time control architecture. The MIC2176
    family operates over an input supply range of 4.5V to 75V
    and can be used to supply up to 15A of output current. The
    output voltage is adjustable down to 0.8V with a guaranteed
    accuracy of ±1%, and the device operates at a constant
    switching frequency of 100kHz, 200kHz, and 300kHz.
    Micrel’s Hyper Speed ControlTM architecture allows for ultrafast transient response while reducing the output capacitance
    and also makes (High VIN)/(Low VOUT) operation possible.
    This digitally modified adaptive tON ripple control architecture
    combines the advantages of fixed-frequency operation and
    fast transient response in a single device.
    The MIC2176 offers a full suite of protection features to
    ensure protection of the IC during fault conditions. These
    include undervoltage lockout to ensure proper operation
    under power-sag conditions, internal soft-start to reduce
    inrush current, fold-back current limit, “hiccup” mode shortcircuit protection and thermal shutdown.
