Title:
パワーオンおよびパワーオフ制御シーケンスをもつ電源アーキテクチャ
Document Type and Number:
Japanese Patent JP2004528798
Kind Code:
A
Abstract:
A power supply apparatus converts an input voltage ( 2 ) into a first ( 3 ) and a second output voltage ( 7 ). The first ( 3 ) and the second output voltage ( 7 ) are put into and/or out of operation sequentially. The power supply apparatus comprises a first converter unit ( 1 ) which converts the input voltage ( 2 ) into the first output voltage ( 3 ), and a second converter unit ( 5 ) for providing the second output voltage ( 7 ). The second converter unit input ( 6 ) is coupled to the first converter unit output ( 3 ). The second converter unit ( 5 ) can only start and provide an output voltage after the first converter unit ( 1 ) has started. During power-down, a sequence is created in which the second converter unit remains operational until any capacitance coupled to the first converter unit output has been discharged.
