    MIC26603-ZA
    28V, 6A Hyper Speed Control
    Synchronous DC-to-DC Buck Regulator
    SuperSwitcher™ II General Description
    The Micrel MIC26603-ZA is a constant-frequency,
    synchronous buck regulator featuring a unique adaptive
    ON-time control architecture. The MIC26603-ZA operates
    over an input supply range of 4.5V to 28V and provides a
    regulated output of up to 6A of output current. The output
    voltage is adjustable down to 0.6V with a guaranteed
    accuracy of ±1%, and the device operates at a switching
    frequency of 600kHz.
    Micrel’s Hyper Speed Control architecture allows for
    ultra-fast transient response while reducing the output
    capacitance and also makes (High VIN)/(Low VOUT)
    operation possible. This adaptive tON ripple control
    architecture combines the advantages of fixed-frequency
    operation and fast transient response in a single device.
    The MIC26603-ZA offers a full suite of 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, foldback current limit, “hiccup mode” short-circuit ...

    MIC26603 - 28V, 6A Hyper Light Load? Synchronous DC/DC Buck Regulator
    Docket ↓
    MIC26603
    28V, 6A Hyper Light Load™
    Synchronous DC/DC Buck Regulator
    SuperSwitcher IIG™ General Description Features The Micrel MIC26603 is a constant-frequency,
    synchronous DC/DC buck regulator featuring adaptive ontime control architecture. The MIC26603 operates over a
    supply range of 4.5V to 28V. It has an internal linear
    regulator which provides a regulated 5V to power the
    internal control circuitry. MIC26603 operates at a constant
    600kHz switching frequency in continuous-conduction
    mode and can be used to provide up to 6A of output
    current. The output voltage is adjustable down to 0.8V. Micrel’s Hyper Light Load™ architecture provides the same
    high-efficiency and ultra-fast transient response as the
    Hyper Speed Control™ architecture under medium to heavy
    loads, but also maintains high efficiency under light load
    conditions
    by
    transitioning
    to
    variable-frequency,
    discontinuous-mode operation.
    The MIC26603 offers a full suite of protection features to
    ensure protection of the IC during fault conditions. These
    include undervoltage lockout to ensure proper operation ...
