Latest Patents

One of Jiun-Chiang Chen's latest patents is a DC-DC converter and voltage conversion method. This invention includes an output unit, a control unit, and a trigger unit. The output unit is designed to convert an input voltage into an output voltage. The control unit generates a control signal based on the input voltage, an output feedback voltage related to the output voltage, and a reference voltage. This allows the output unit to produce the desired output voltage. The trigger unit generates a first trigger signal based on the control signal, output feedback voltage, and reference voltage. When the output feedback voltage falls below the reference voltage by a preset amount, the control unit initiates a voltage-regulating process to adjust the output voltage in advance.

Another significant patent is for a switching power converter. This invention comprises an upper-bridge switch, a lower-bridge switch, an impedance circuit, a first control circuit, a second control circuit, and a logic circuit. The impedance circuit generates an output voltage and a sensing current based on the conductive state of the upper and lower bridge switches. The first control circuit produces a first pulse signal according to the output voltage. The second control circuit operates in two modes, generating a second pulse signal and a third pulse signal, respectively. It employs different threshold values in each mode to determine mode switching, creating a hysteretic effect. The logic circuit manages the upper-bridge switch using the first pulse signal and controls the lower-bridge switch with either the second or third pulse signal.
