    MIC23051
    4MHz PWM Buck Regulator with
    HyperLight Load™ and Voltage Scaling General Description Features The Micrel MIC23051 is a high efficiency 600mA PWM
    HyperLight Load™ Input voltage: 2.7V to 5.5V
    synchronous buck (step-down) regulator featuring 600mA output current
    HyperLight Load™, a patented switching scheme that Fixed output voltage from 0.72V to 3.3V
    offers best in class light load efficiency and transient Output voltage scaling option
    performance while providing very small external Ultra fast transient response
    components and low output ripple at all loads. 20µA typical quiescent current
    The MIC23051 has an output voltage scaling feature that
    can toggles between two different voltage levels. 4MHz in CCM PWM operation in normal mode
    The MIC23051 also has a very low typical quiescent 0.47µH to 2.2µH inductor
    current draw of 20µA and can achieve over 85% efficiency Low voltage output ripple
    even at 1mA. The device allows operation with a tiny
    – 25mVpp in HyperLight Load mode
    inductor ranging from 0.47µH to 2.2µH and uses a small
    – 3mV output voltage ripple in full PWM mode
    output capacitor that enables a sub-1mm height solution. >93% efficiency
    In contrast to traditional light load schemes HyperLight ~85% at 1mA
    Load™ architecture does not need to trade off control
    speed to obtain low standby currents and in doing so the Micropower shutdown
    device only needs a small output capacitor to absorb the Available in 8-pin 2mm x 2mm MLF®
    load transient as the powered device goes from light load –40°C to +125°C junction temperature range ...
