Abstract:
A switching power supply device has both a turn-on timing modulation function and a turn-off timing modulation function, performs the turn-off timing modulation in a PFM control region and the turn-on timing modulation in a PWM control region, and further continues at least one of the modulations even after the PFM control and the PWM control are switched from one to the other, to achieve a stable operation of the switching power supply device at the control switching boundary without significantly decreasing the modulation effect of frequency jitter control.

Claim (Index 2):
The switching power supply device according to  claim 1 ,\n wherein the switching control circuit performs at least one of the following: when switching the frequency changing control mode to the frequency fixing control mode, gradually decreasing a modulation amplitude in the first modulation control until the frequency changing control mode is switched to the frequency fixing control mode; and when switching the frequency fixing control mode to the frequency changing control mode, gradually decreasing a modulation amplitude in the second modulation control until the frequency fixing control mode is switched to the frequency changing control mode.
