ABSTRACT:
The present invention relates to a multi-period cycle-alternative switching mode power supply control device and its control method, and the device comprises: a power transfer control unit, a dimming bias control, a burst timing control, and a steering logic; and the method is a power control method that uses a burst timing control to produce an ON_OFF (High_Low) control timing, and after regulated power with a different amplitude is added to the OFF period of the burst period between two ON_OFF periods, two or more mixed periods are used to regulate the timing to a highly reliable and a broad dynamic range. The device of the invention can effectively control certain power transfer components of specific nature and assure that those components and the loading at the rear end can operate more efficiently in a reliable range of a specific nature.
