    MIC24051 - 12V, 6A High-Efficiency Buck Regulator
    Docket ↓
    12V, 6A High-Efficiency Buck Regulator
    with Hyper Speed ControlВ®
    Features General Description Hyper Speed ControlВ® Architecture Enables:
    -High Delta V Operation (VIN = 19V and VOUT
    = 0.8V)
    -Small Output Capacitance 4.5V to 19V Voltage Input 6A Output Current Capability, up to 95%
    Efficiency Adjustable Output from 0.8V to 5.5V ±1% Feedback Accuracy Any Capacitor Stable -Zero-to-High ESR 600 kHz Switching Frequency No External Compensation Power Good (PG) Output Foldback Current-Limit and “Hiccup Mode”
    Short-Circuit Protection Supports Safe Start-Up into a Pre-Biased Load –40°C to +125°C Junction Temperature Range Available in a 28-pin 5 mm x 6 mm QFN Package The MIC24051 is a constant-frequency, synchronous
    buck regulator featuring a unique adaptive on-time
    control architecture. The MIC24051 operates over an
    input supply range of 4.5V to 19V and provides a
    regulated output of up to 6A of output current. The
    output voltage is adjustable down to 0.8V with a
    guaranteed accuracy of В±1%, and the device operates
    at a switching frequency of 600 kHz.
    Microchip’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. ...
