DC-DC converter capable of configuring topology |
摘要 |
Disclosed is a DC-DC converter including: a switch unit controlling a flow of a current based on a buck-boost topology; a short circuit unit short circuited or opened according to an external setting to change a topology of the switch unit; an inductor storing a current induced by the switch unit; a topology selecting unit selecting a topology in response to an external input signal and generating a signal corresponding to the selected topology; a pulse width modulating unit generating a signal for determining an operation time of the switch unit; a reverse flow detecting unit detecting a reverse flow of a current flowing through the switch unit to generate a signal; and a switch control unit controlling the switch unit in response to signals of the topology selecting unit, the pulse width modulating unit and the reverse flow detecting unit. |

1. A DC-DC converter comprising:
a switch unit controlling a flow of a current based on a buck-boost topology; a short circuit unit short circuited or opened according to an external setting to change a topology of the switch unit; an inductor storing a current induced by the switch unit; a topology selecting unit selecting a topology in response to an external input signal and generating a signal corresponding to the selected topology; a pulse width modulating unit generating a signal for determining an operation time of the switch unit; a reverse flow detecting unit detecting a reverse flow of a current flowing through the switch unit to generate a signal; and a switch control unit controlling the switch unit in response to signals of the topology selecting unit, the pulse width modulating unit and the reverse flow detecting unit. |
