The MAX17222 offers a 400mV to 5.5V input range, a 0.5A peak inductor current limit, and an output voltage that is selectable using a single standard 1% resistor. A novel True Shutdown ™ mode yields leakage currents in the nanoampere range, making this a truly nanoPower device!

WebIn this project we experiment with a new type of power transistor, the GaN FET, for improving effiency in a simple buck converter. The GaN FET is an ideal transistor for low to medium power applications because it has a very small gate charge and no reverse recovery charge, leading to rapid switching times and reduced switching losses. WebS swings to ground during that time, as it does in most applications). Since the capacitor is charged from a low voltage source the power consumed to drive the gate is small. The input commands for the high-side channel have to be level-shifted from the level of COM to whatever potential the tub is floating at which can be as high as 1200 V.
