Latest Patents
Ming-Chien Li's latest patents include a DC-DC converter with auto-switching between pulse width modulation (PWM) and pulse frequency modulation (PFM). This innovative converter is designed for use in OLED displays, where it judges the power consumption of the OLED array based on display data. The converter features a content statistic unit, an auto-switching control unit, a PWM controller, a PFM controller, and a power generator. The content statistic unit accumulates display data and outputs a statistic value, which the auto-switching control unit uses to determine the appropriate mode of operation.
Another significant patent by Li is a power supply with a pulse frequency modulating circuit that calculates logic state changes. This method stabilizes voltage by providing a comparing signal that adjusts based on the logic state of the voltage being stabilized. The process involves setting the comparing signal to a first logic state when the voltage is below a preset level and adjusting the enable time of the pulse signal accordingly.
