  • HIGH-EFFICIENCY CONVERTER WITH A CONFIGURABLE SWITCHING ELEMENT
    Publication number: 20250112553
    Abstract: According to an embodiment, a method of operating an M-level buck converter in a battery charging circuit is provided. The M-level buck converter includes 2×N×(M?1) number of transistors. M and N are greater than one. The method includes operating the M-level buck converter in a first mode of the battery charging circuit corresponding to a high-current charge mode. The method further includes operating the M-level buck converter in a second mode of the battery charging circuit corresponding to a low-current charge mode. In the first mode, 2×N×(M?1) number of transistors are switched ON and OFF. In the second mode, 2×(M?1) number of transistors are switched ON and OFF and 2×N×(M?1)?2×(M?1) number of transistors are fully deactivated.

  • Interface latch for data level transfer
    Patent number: 6522168
    Abstract: An interface for translating data of different voltages includes an input terminal structured to accept an input from a circuit supplied by a power supply having a first voltage level, as well as an output terminal structured to provide an output from the interface a first circuit portion powered by a power supply having the first voltage level, a second circuit portion is powered by a power supply having a second voltage level, and a power supply detection circuit structured to accept a detection signal and to maintain a correct output at the output terminal even after the power supply having the first voltage level no longer supplies the first voltage level to the interface.
