Power supply device having multiple outputs

A power supply having a plurality of outputs are provided. The invention of claim 1 for controlling the power supplied to the primary winding of the transformer in accordance with the first output circuit, the first output power to generate a first output power with respect to the power delivered to the transformer, the secondary side of the transformer in the power supply having a plurality of outputs including an output control unit, the second to the N-th output circuit for generating a second to the N-th output power with respect to the power delivered to the secondary side of the transformer, respectively; And a power supply having multiple outputs comprising the second to the N output control section which controls the output of the second to the first to feedback the N output power, respectively 2 to the N-th output power linearly relate to. According to the invention, it can be respectively controlled independently of a multi-output circuit of the transformer secondary side which can be provided with at least one or more and, particularly, by controlling a linear, stable control of the output power according to the multiple-output for the implementation of a multiple-output to enable.
