Microchip’s highly integrated MIC45404 Step-Down power module solution is designed to simplify the system power design process while offering exceptional performance. The MIC45404 offers a complete switching power supply solution in a compact, low profile, thermally enhanced, rugged QFN package. This power module integrates a PWM controller, power MOSFETs, inductor, and associated discrete passive components to preserve board space and reduce component count. It also meets the demanding CISPR22, CLASS B EMI standards, further reducing design complexity.
