MIC4575 200kHz Simple 1A Buck Regulator

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. The MIC4575 is available in 3.3V, and 5V fixed output versions or a 1.23V to 20V adjustable output version. Both versions are capable of driving a 1A load with excellent line and load regulation.
