Abstract: A power safety system includes a first MOS, a second MOS, a switch and a body controller. The first MOS is connected between a power input and a power output. The second MOSFET is connected between the power output and a charging output. The switch has an end connected to the body of the first MOS, and the opposite end switched between the source and the drain of the first MOS. A body controller controls the switch according to the voltage at the power input and the voltage at the power output, to connect the body of the first MOS to the source or the drain of the first MOS. By switching the switch, the first MOS will have a parasitic diode effective to prevent a reverse current from the power output to the power input.

Abstract: In a PWM signal generation method of a voltage regulator, an output sense signal, a first ramp signal and a second ramp signal are provided. A first time point of the first ramp signal crossing with the output sense signal is used to determine a start point of an ON-time of a PWM signal, and a second time point of the second ramp signal crossing with the output sense signal is used to determine an end point of the ON-time of the PWM signal. Moreover, the first ramp signal is reset to a reference voltage at the first time point and then maintained at the reference voltage, and further ramps down starting from the end point of the ON-time. The second ramp signal ramps up starting from the start point of the ON-time, and then is reset to a preset voltage at the second time point.

Abstract: A current regulator includes a first current source to provide a reference current varying with a dimming step, and a second current source to generate a drive current for a white LED according to the reference current. The reference current and the dimming step have a relationship identical to or approximating a relationship between luminance and lightness perceived by human eyes. Thus, the white LED is controlled to have a linear variation of the luminance perceived by human eyes when the dimming step is changed.

Abstract: An electronic package structure and method use a conductive strip to bond die-to-die, die-to-lead, chip carrier-to-lead, or lead-to-lead. A conductive strip may carry greater current than a bonding wire, and thus may replace several bonding wires. The bonding of the conductive strip may be carried out by an SMT process, and thus requires lower cost than wire bonding processes. A conductive strip may be bonded to more than two dice or leads to save more bonding wires. A conductive strip is stronger than a bonding wire, and thus lowers the possibility of being broken.

Abstract: A multi-channel regulator system includes serially connected PWM integrated circuits, each of which determines a PWM signal for a respective channel to operate therewith, and individually controls its operation mode according to whether or not an external clock is detected. Therefore, each channel will not be limited to operate under a constant mode and could become a master channel or a slave channel. Additionally, each of the PWM integrated circuits generates a phase shifted synchronous clock for its next channel during it is enabled, and thus all the channels operate in a synchronous but phase interleaving manner.
