Abstract
The switching converter equipped with negative current tracking control includes a switching transistor whose drain is connected to an input power supply, a rectifying transistor whose drain is connected to a source of the switching transistor and whose source is connected to a ground, an inductor having one end connected to the source of the switching transistor and the drain of the rectifying transistor, an output capacitor having a first end connected to the other end of the inductor and a second end connected to a ground, a PWM controller that outputs a PWM control signal to a gate of the switching transistor and a gate of the rectifying transistor, a zero current detector that detects zero crossing of an inductor current flowing through the inductor, and a negative current tracking controller that variably adjusts an offset of the zero current detector.
