MIC45404 Evaluation Board (MIC45404YMP-EV)

The MIC45404 device is a 19V, 5A ultra-low profile, synchronous step-down regulatormodule optimized for high efficiency at low output voltages. The module incorporatesa DC-to-DC regulator, bootstrap capacitor, high-frequency input capacitor and aninductor in a single package. The module pinout is optimized to simplify the PrintedCircuit Board (PCB) layout process. This highly integrated solution expedites systemdesign and improves product time to market. The internal MOSFETs and inductor areoptimized to achieve high efficiency at low output voltage. Due to the fully optimizeddesign, MIC45404 can deliver up to 5A current with a wide input voltage rangeof 4.5V to 19V.
