MIC23051
Description
The MIC23051 is a high efficiency 600 mA PWM synchronous buck (step-down) regulator featuring HyperLight 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 toggles between two different voltage levels.
