    MIC2182 Micrel MIC2182
    High-Efficiency Synchronous Buck Controller General Description Features Micrel’s MIC2182 is a synchronous buck (step-down) switching regulator controller. An all N-channel synchronous architecture and powerful output drivers allow up to a 20A output
    current capabilty. The PWM and skip-mode control scheme
    allows efficiency to exceed 95% over a wide range of load
    current, making it ideal for battery powered applications, as
    well as high current distributed power supplies.
    The MIC2182 operates from a 4.5V to 32V input and can
    operate with a maximum duty cycle of 86% for use in lowdropout conditions. It also features a shutdown mode that
    reduces quiescent current to 0.1ВµA.
    The MIC2182 achieves high efficiency over a wide output
    current range by automatically switching between PWM and
    skip mode. Skip-mode operation enables the converter to
    maintain high efficiency at light loads by turning off circuitry
    pertaining to PWM operation, reducing the no-load supply
    current from 1.6mA to 600ВµA. The operating mode is internally selected according to the output load conditions. Skip
    mode can be defeated by pulling the PWM pin low which
    reduces noise and RF interference.
    The MIC2182 is available in a 16-pin SOP (small-outline
    package) and SSOP (shrink small-outline package) with an
    operating range from –40°C to +85°C. 4.5V to 32V Input voltage range
