MIC23051 Datasheet | Micrel Semiconductor

MIC23051 .. 4MHz PWM Buck Regulator with HYPER LIGHT LOAD™ and Voltage Scaling General Description The Micrel MIC23051 is a high efficiency 500mA PWM synchronous buck (step-down) regulator featuring Hyper Light Load™, a patented switching scheme that offers best in class light load efficiency and transient performance while providing very small external ponents and low output ripple at all loads. The MIC23051 has an output voltage scaling feature that can toggles between two different voltage levels. The MIC23051 also has a very low typical quiescent current draw of 20µA and can achieve over 85% efficiency even at 1mA. The device allows operation with a tiny inductor...
