Abstract:
A switching regulator having adjustable inductor current threshold employs a control method which includes: (S 1 ) determining whether an output voltage is greater than a reference voltage or determining whether a switching frequency of the power stage is smaller than a predetermined lower frequency limit, and (S 2 ) when it is determined yes in the step (S 1 ), adjusting the inductor current threshold, such that the switching regulator operates under a pseudo discontinuous conduction mode (PDCM) wherein the switching frequency is not smaller than the predetermined lower frequency limit. Consequently, when the switching regulator operates under a light load mode, an optimum balance between a total power consumption and switching noise interference will be ensured.

Claim (Index 8):
A switching regulator which has an adjustable inductor current threshold, wherein the switching regulator is configured to operably convert an input power to an output power and supply the output power to an external load; the switching regulator comprising:\n a power stage including an inductor, a first power transistor and a second power transistor, which are coupled to one another; and a pulse width modulation (PWM) controller, which is configured to operably control the first power transistor and the second power transistor to convert the input power to the output power; wherein, when an inductor current reaches an inductor current threshold, the PWM controller turns OFF the first power transistor and the second power transistor; wherein, the PWM controller includes: a driver circuit, which is configured to operably control the first power transistor and the second power transistor according to a PWM signal; and an operation circuit, which is configured to operably generate the PWM signal, wherein the operation circuit is configured to determine whether an output voltage is greater than a reference voltage or determining whether a switching frequency of the power stage is smaller than a predetermined lower frequency limit; when the output voltage is greater than the reference voltage or when the switching frequency of the power stage is smaller than the predetermined lower frequency limit, the operation circuit adjusts the inductor current threshold such that the switching regulator operates under a pseudo discontinuous conduction mode (PDCM) wherein the switching frequency is not smaller than the predetermined lower frequency limit.
