    4MHz PWM Buck Regulator with
    HyperLight Loadв„ў Switching Scheme General Description Features The Micrel MIC23050 is a high-efficiency, 600mA, PWM, Input voltage: 2.7V to 5.5V
    HyperLight Loadв„ў
    synchronous buck (step-down) regulator featuring the 600mA output current
    HyperLight Loadв„ў patented switching scheme that offers Fixed output voltage from 0.72V to 3.3V
    best-in-class light load efficiency and transient Ultra-fast transient response
    performance while
    external 20ВµA typical quiescent current
    components and low output ripple at all loads. 4MHz in PWM in constant-current mode
    The MIC23050 also has a very-low typical quiescent
    current draw of 20ВµA and can achieve over 89% efficiency 0.47ВµH to 2.2ВµH inductor
    even at 1mA. The device allows operation with a tiny Low voltage output ripple
    inductor ranging from 0.47ВµH to 2.2ВµH and uses a small
    -25mVPP in HyperLight Loadв„ў mode
    output capacitor that enables a sub-1mm height.
    -3mV output voltage ripple in full PWM mode
    In contrast to traditional light load schemes, the HyperLight >93% efficiency
    Loadв„ў architecture does not need to trade off control ~89% at 1mA
    speed to obtain low standby currents and in doing so the
    device only needs a small output capacitor to absorb the Micropower shutdown ...
