Product Details
The MIC33050 is a high efficiency 600mA PWM synchronous buck (step-down) regulator with internal inductor featuring HyperLight 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 MIC33050 also has a very low typical quiescent current draw of 20μA and can achieve over 83% efficiency even at 1mA.
