  • SMPS control IC with 4 terminals
    Patent number: 8804385
    Abstract: A switching converter IC without a built-in power switching device includes a first terminal serving as a power supply positive connection, a second terminal serving as a power supply return connection, a third terminal serving as the switch-driving connection for controlling the switching duty of an external bipolar or MOSFET power switching device and also serving as a conduit for detection of current drawn by the power switching device to thereby provide overcurrent protection. Feedback information is derived from voltage between the first and the second terminals.
    Type: Grant
    Filed: August 8, 2011
    Date of Patent: August 12, 2014
    Assignee: Mosway Semiconductor Limited
    Inventors: Chiu-Sing Celement Tse, On-Bon Peter Chan, Chik-Yam Lee, Chi-Keung Tang, Chi-Ken Kenny Lee
