POWER SWITCHING DRIVING APPARATUS, AND POWER FACTOR CORRECTION DEVICE AND POWER SUPPLY DEVICE HAVING THE SAME |
摘要 |
There are provided a power switching driving apparatus able to reduce a circuit area and increase a driving speed, and a power factor correction device and a power supply device having the same. The power switching driving apparatus includes: a first driving unit providing a switching signal in response to a control signal from the outside; a second driving unit including first and second NMOS FETs cascode-connected between an operational power source terminal supplying pre-set operation power and a ground, and performing switching complimentarily in response to the switching signal to provide a switching control signal controlling power switching; a current supply unit supplying a current for driving the second driving unit; and a voltage maintaining unit maintaining a voltage for driving the second driving unit.
