Floating ground buck converter

WebSRC) used by the floating driver to drive the external NMOS buck switch. This pin should be bypassed with a high quality ceramic capacitor. PIN DESCRIPTIONS The UC3578 Floating Buck Controller is a high frequency switching regulator with a floating driver which provides PWM control for non-isolated buck converters. The con- 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.
