LED driving circuit and a MOSFET switch module thereof |
摘要 |
An LED driving circuit and a MOSFET switch module thereof is disclosed, and the MOSFET switch module which is used to control a current of the LED driving circuit. The present invention employs a voltage clamping device to clamp the voltage level of the drain of transistor in the MOSFET switch module when being turned off. Via this way, the requirement for the withstand voltage of the transistor is lowered, and so the cost and power consumption thereof is reduced. |
