Description

General part information

MIC33050 Series

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.

In contrast to traditional light load schemes, the HyperLight Load® architecture does need not 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 full load.
