    2MHz PWM Synchronous Buck
    Regulator with LOWQ Mode and Voltage
    Scaling General Description Features The Micrel MIC2206 is a high efficiency 2MHz PWM
    synchronous buck (step-down) regulator that
    features a LOWQ™ LDO standby mode that draws
    only 18µA of quiescent current. The MIC2206
    allows an ultra-low noise, small size, and high
    efficiency solution for portable power applications.
    In PWM mode, the MIC2206 operates with a
    constant frequency 2MHz PWM control. Under light
    load conditions, such as in system sleep or standby
    modes, the PWM switching operation can be
    disabled to reduce switching losses. In this light
    load LOWQ™ mode, the LDO maintains an output
    voltage of 1V and draws only 18µA of quiescent
    current. The LDO mode of operation saves battery
    life while not introducing spurious noise and high
    ripple as experienced with pulse skipping or bursting
    mode regulators.
    The MIC2206 operates from 2.7V to 5.5V input and
    features internal power MOSFETs that can supply
    up to 600mA output current in PWM mode. It can ...
