... 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 2:1 reduction in output filter inductor size. The MIC4575 is available in 3.3V, and 5V fixed output versions ...
