摘要： A switch-mode converter includes a high-side driver, a high-side transistor, a low-side driver, a low-side transistor, a capacitor, and an active diode. The high-side driver is supplied by the bootstrap voltage of the bootstrap node and a floating reference voltage of a floating reference node, and generates the high-side output signal. The high-side transistor provides an input voltage to the floating reference node according to the high-side output signal. The low-side driver generates the low-side output signal. The low-side transistor couples the floating reference node to a ground according to the low-side output signal. The capacitor is coupled between the bootstrap node and the floating reference node. The active diode provides the supply voltage to the bootstrap node. When the bootstrap voltage exceeds the supply voltage, the active diode isolates the supply voltage from the bootstrap node.

摘要： A power supply device has an output portion that generates an output voltage from an input voltage and supplies the output voltage to a load, an output feedback controller that drives the output portion by performing output feedback control, and a first detector that detects, by means of an electromagnetic induction method, a change in a first monitoring target current due to a load change. The output feedback controller reflects a detection result from the first detector into the output feedback control.
