Beschreibung
Zusammenfassung:	The invention discloses a switched power supply. The traditional external inductor is replaced with an equivalent inductor of a bonding wire, and meanwhile, a current control pulse width modulator and a current control pulse frequency modulator are applied to carrying out high-frequency switching operation so as to match with a low inductance value of the bonding wire. By applying the invention, the effects of reducing cost and power consumption and complexity can be achieved.
