Switching power supply apparatus
Abstract:
In a switching power supply apparatus, a main switching control circuit performs switching control of a low-side switch device and a high-side switch device based on a feedback signal corresponding to a main output voltage output from a secondary winding of a transformer, and applies and stops applying a voltage to a primary winding of the transformer. A digital signal processor, in accordance with the load status of the main load, changes set target values, performs switching control of switch devices of the sub-rectifying and smoothing circuits, and drives sub-loads.
