General Description

The MIC4575 is a series of easy to use fixed and adjustable BiCMOS step-down (buck) switch-mode voltage regulators.

The 200kHz MIC4575 duplicates the pinout and function of the 52kHz LM2575.

The higher switching frequency may allow up to a 2:1 reduction in output filter inductor size.
