MIC45212-2

MIC45212-1/-2 26V/14A DC-to-DC Power Module General Description Micrel’s MIC45212 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. The internal MOSFETs and inductor are optimized to achieve high efficiency at a low output voltage. The fully-optimized design can deliver up to 14A current under a wide input voltage range of 4.5V to 26V, without requiring additional cooling. The MIC45212-1 uses Micrel’s HyperLight Load® (HLL) while the MIC45212-2 uses Micrel’s Hyper Speed Control™ architecture, which enables ultra-fast load transient response, allowing for a reduction of output capacitance. The MIC45212 offers 1% output accuracy that can be ...
