    MIC28515
    75V/5A Hyper Speed Control®
    Synchronous DC/DC Buck Regulator with External Mode Control
    Features General Description Hyper Speed Control® Architecture Enables:
    -High Input to Output Voltage Conversion
    Ratio Capability (VIN = 75V and VOUT = 0.6V)
    -Small Output Capacitance 4.5V to 75V Input Voltage 5A Output Current Capability with up to 95% Efficiency Adjustable Output Voltage from 0.6V to 32V Selectable HLL or CCM operation ±1% FB Accuracy Any Capacitor™ Stable:
    -Zero-ESR to High-ESR Output Capacitors 270 kHz to 800 kHz Adjustable Switching Frequency Internal Compensation Built-In 5V Regulator for Single-Supply Operation Auxiliary Bootstrap LDO for Improving System
    Efficiency Internal Bootstrap Diode Programmable Current Limit Hiccup Mode Short-Circuit Protection Thermal Shutdown Supports Safe Start-Up into a Prebiased Output –40°C to +125°C Junction Temperature Range Available in 32-Pin, 6 mm x 6 mm VQFN Package The MIC28515 is an adjustable frequency,
    synchronous buck regulator that features a unique
    adaptive on-time control architecture. The MIC28515
    operates over an input supply range of 4.5V to 75V, and
    provides a regulated output of up to 5A of output
    current. The output voltage is adjustable down to 0.6V
    with an accuracy of ±1%.
    Hyper Speed Control architecture allows for an ultra-fast
    transient response, while reducing the output
    capacitance, and also makes high-VIN/low-VOUT
    operation possible. This adaptive on-time control
    architecture combines the advantages of fixed
    frequency operation and fast transient response in a
    single device.
    The operating mode under light load conditions can be ...
