Microchip, MIC23050-SYML-TR Switching Regulator, 1-Channel 600mA 8-Pin, MLF

The Microchip MIC23050-SYML-TR is a high efficiency 600mA PWM synchronous buck (step-down) regulator featuring Hyper Light Load®, a patent pending 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 MIC23050-SYML-TR has a very low typical quiescent current draw of 20μA and can achieve over 89% efficiency even at 1mA. The device allows operation with a tiny inductor ranging from 0.47μH or 2.2μH while using small output capacitors, enabling a sub 1mm height solution. In contrast to traditional light load schemes Hyper Light Load® architecture does not need to trade off control speed to obtain low standby currents and in doing so the device only needs a small output capacitor to absorb the load transient as the powered device goes from light load to
