Abstract: D e s ig n S o l u t io n 1 2 0 0 k H z S w itching R egulator R educes B oard S pace by Brian Huffman The Micrel MIC4574, MIC4575 and MIC4576 are enhanced versions of the popular LM257x family of 52kHz, step-down (buck), switching regulators. They feature a 200kHz switch ing frequency that reduces the inductor size by a factor of four, freeing up precious board space, and allows conversion from 12V to 5V/1A in under one square inch of board space. The MIC457x series operates from input voltages -
