APPARATUS FOR SUPPLYING MULTI-OUTPUT AND DISPLAY APPARATUS USING THE SAME
First Claim
1. A multi output power supply apparatus, the multi output power supply apparatus comprising:
- an input power unit which generates an LLC resonance signal by using DC power;
a primary output power unit which outputs a first output voltage based on a first voltage induced in response to the LLC resonance signal;
a secondary output power unit which outputs a second output voltage based on a second voltage induced in response to the LLC resonance signal; and
a power control unit which controls the input power unit to change the LLC resonance signal so that the first output voltage has a preset level, and controls the secondary output power unit so that the second output voltage has a preset level irrespective of a change in a level of the first output voltage.
