Latest Patents

One of Liu's latest patents is titled "Buck converter and control method therefor." This invention provides a pair of NMOSFET switches connected in series, along with an output filter, a control circuit, a boot-strap capacitor, and a disabling circuit. The high-side MOSFET switch is coupled to an input voltage, while the low-side MOSFET switch is connected to the ground. These switches operate with complementary duty cycles, and the output filter is designed to provide a stable output voltage. The boot-strap capacitor plays a crucial role in ensuring that the gate voltage of the high-side MOSFET switch exceeds the input voltage. Additionally, the disabling circuit monitors the voltage across the boot-strap capacitor and generates a control signal to turn off the high-side MOSFET switch when necessary.

Another significant patent by Liu is the "Method and device for delaying activation timing of output device." This invention outlines a delay method for determining the activation time of an output device within a circuit system. The method involves assessing the resistance of an over-current flag pull-high resistor, generating a current based on this resistance, and using it to determine the activation current and timing for the output device.
