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. WebJun 7, 2016 · The versatile single, low-side power switch architecture can be used to power floating output step-up and step-down converters such as boost-buck and single inductor buck-boost mode. The LED string’s voltage reference to ground is not necessary since LED output is visible light only.
