Product Details
MIC45205 is a synchronous step-down regulator module, featuring a unique adaptive ON-time control architecture. The module incorporates a DC-to-DC controller, power MOSFETs, bootstrap diode, bootstrap capacitor, and an inductor in a single package, simplifying the design and layout process for the end user. This highly-integrated solution expedites system design and improves product time-to-market.
