Switched-mode power supply supporting burst-mode operation |
摘要 |
A switched-mode power supply (SMPS) that operates in a burst mode when an electronic device that receives power from the SMPS demands a low level of power as when in a stand-by mode or cut-off mode. The SMPS contains a first power supply unit for receiving a power and rectifying it, and, according to a level of an output for the load, distinguishing between a normal mode and a burst mode to perform switching according to a timing corresponding to the normal mode and the burst mode to supply a first power. The SMPS also contains an output power supply unit for receiving the first power from the first power supply unit according to a winding ratio of a coil to generate a power for driving the load.
