Patent for Power Converter Control Invention Issued to O2Micro
GEORGE TOWN, Grand Cayman, June 13, 2012 (GLOBE NEWSWIRE) -- O2Micro®International Limited (Nasdaq:OIIM) was issued 23 claims under United States patent number 8,179,105 for its Power Converter Current Control invention.
This patented invention offers a method to accurately control the battery charger's charging current in the low current range, which is especially difficult using traditional architectures.
"The patented power converter's output current can be accurately controlled in the low current range, avoiding the inaccuracies caused by the current sense amplifier's offset," remarked Laszlo Lipcsei, vice president at O2Micro. "This is especially important when charging currents are very small, e.g., during wake up or end of charging."
