MIC4574 Datasheet PDF (200kHz Simple 0.5A Buck Voltage Regulator)

MIC4574 - 200kHz Simple 0.5A Buck Voltage Regulator

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.

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 versions, within specified voltages and load conditions.
