    MIC2166
    Adaptive On-Time DC-DC Controller
    Hyper Speed Control™ Family General Description Features The Micrel MIC2166 is a synchronous adaptive on-time
    buck controller targeting high-performance, cost-sensitive
    applications such as set-top boxes, gateways, routers,
    computing
    peripherals,
    and
    telecom/networking
    equipment.
    The MIC2166 operates over a supply range of 4.5V to
    28V. It has an internal linear regulator which provides a
    regulated 5V supply to power the internal control circuitry.
    MIC2166 operates at a constant 600kHz switching
    frequency and can be used to drive up to 25A of output
    current. The output voltage is adjustable from 0.8V to
    5.5V.
    A unique Hyper Speed Control™ architecture enables
    ultra-fast transient response while reducing the output
    capacitance and also makes High VIN/Low VOUT operation
    possible.
    A UVLO feature is provided to ensure proper operation
    under power-sag conditions to prevent the external power ...
