    MIC24052 - 12V, 6A High-Efficiency Buck Regulator
    Docket ↓
    12V, 6A High-Efficiency Buck Regulator
    with HyperLight LoadВ®
    Features General Description HyperLight LoadВ® Efficiency: up to 80% at 10 mA Hyper Speed ControlВ® Architecture Enables:
    -High Delta V Operation (VIN = 19V and VOUT
    = 0.8V)
    -Small Output Capacitance 4.5V to 19V Input Voltage Range 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 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 MIC24052 is a constant-frequency, synchronous
    DC/DC buck regulator featuring a unique adaptive
    on-time control architecture. The MIC24052 operates
    over an input supply range of 4.5V to 19V. It has an
    internal linear regulator which provides a regulated 5V
    to power the internal control circuitry. The MIC24052
    operates at a constant 600 kHz 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.
    Microchip’s HyperLight Load® architecture provides
    the same high-efficiency and ultra-fast transient
    response as the Hyper Speed ControlВ® architecture
    under medium to heavy loads, but also maintains high
    efficiency under light load conditions by transitioning to
    variable-frequency, discontinuous-mode operation. ...
