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 1):
A control method of 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 a pulse width modulation (PWM) controller and a power stage, the power stage including: an inductor, a first power transistor and a second power transistor, which are coupled to one another, the PWM controller being 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, the control method of the switching regulator having the adjustable inductor current threshold comprising the steps of:\n (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.
