  • Start-up in-rush current protection circuit for DCDC converter
    Patent number: 8264807
    Abstract: A protection circuit for protecting DCDC converter with a power MOS transistor from start-up in-rush current includes a coupling capacitor and a voltage clamping circuit. By using the coupling capacitor to turn-off the power MOS transistor, there is no current consumed during the normal operation of the circuit. Enable signal or leakage current circuit is used to discharge the capacitor so that the circuitry can work in another turning-on of power supply.
    Type: Grant
    Filed: March 26, 2010
    Date of Patent: September 11, 2012
    Assignees: Panasonic Corporation, Panasonic Semiconductor Asia Pte. Ltd.
    Inventors: Wee Sien Hong, Jiong Fu, Andi Soemarli Rasak Lie
