Overview

MIC4574 Micrel, Inc.
MIC4574 200kHz Simple 0.
5A Buck Regulator General Description The MIC4574 is a series of easy to use fixed and adjustable BiCMOS step-down (buck) switch-mode voltage regulators.
The 200kHz MIC4574 duplicates the pinout and function of the 52kHz LM2574.
The higher switching frequency may allow up to a 2:1 reduction in output filter inductor size.
The MIC4574 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 0.
5A load with excellent line and load regulation.
The feedback voltage is guaranteed to ±2% tolerance for adjustable versions, and the output voltage is guaranteed to ±3% for fixed ...
