ABSTRACT:
Output voltage of a switching regulator is rectified and adjusted by the internal body diode of an FET. When the output voltage exceeds a reference voltage, the FET is gated off, causing the internal body diode to reduce the output voltage by a diode drop. When the FET is turned on, the diode is shorted and, as a result, the output voltage is increased by a finite amount of additional energy. This adjustment range, a diode drop, is significant for low voltage, wide bandwidth power supplies.
