MIC23051 4MHz PWM Buck Regulator With HYPER LIGHT LOAD™ And Voltage Scaling

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 components 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 20A and CAN achieve over 85% efficiency even at 1mA. The device allows operation with a tiny inductor ranging from 0.47H to 2.2H and uses a smal output capacitor that enables a sub-1mm height. By Micrel Semiconductor
