Latest Patents
One of Liu's key patents is titled "Pulse width modulation regulator IC and circuit thereof." This invention provides a pulse width modulation regulator integrated circuit (IC) designed to control the duty cycle of at least one switch. The primary function of this IC is to convert an input voltage signal into an output voltage. It features an input pin that receives an input signal distinct from the input voltage signal. Notably, the input signal has a duration that closely matches the time the input voltage signal remains at a high level, although the waveforms of the two signals differ. The IC converts the input signal into a square wave signal through a conversion unit, and a PWM signal is generated by a PWM controller based on this square wave signal to manage the duty cycle of the switch. This design allows for the adjustment of internal or external circuits of the IC to accommodate various input signals without the need to increase the number of input pins.
