摘要： In a fly-back voltage converter that includes a transformer to transform a primary current to a secondary current and a switch serially coupled to the primary winding to switch the primary current in response to a control signal, a detection signal is produced by comparing the secondary current with two threshold values after the primary current is switched off to trigger the next on-time cycle of the switch. Once the secondary current is detected to be greater than a first threshold value, it is determined that the secondary current has been switched on, and until the secondary current is detected to be lower than a second threshold value, it is determined that the secondary current is to be switched off. The hysteresis range of the threshold values prevents error detection of the secondary current.

摘要： A plurality of switches, an inductor and two capacitors are configured to be a boost-inverting converter. To operate the converter in a boost-inverting mode, a control apparatus and method switch the switches such that the inductor is energized in a first phase, the first capacitor is discharged to produce an inverting voltage in a second phase, and the second capacitor is charged to produce a boost voltage in a third phase. Therefore, the boost-inverting converter has lower peak inductor current and less power loss, and the limitation to the switch design for the boost-inverting converter is relaxed.

摘要： An offset current independent sense circuit is switchable between a store state and a sense state. In the store state, the sense circuit stores an offset current to a capacitor, and the influence of the offset current is eliminated by a transistor to regenerate the offset current based on a signal provided by the capacitor in the sense state.

摘要： A switching mode voltage regulator comprises a pulse width modulator and an adjustable one-shot circuit to generate an adjustable signal based on an input voltage, an adjustable voltage, and a PWM signal from the pulse width modulator at light loading to switch a high-side switch of an output stage in the voltage regulator. The ON duty of the adjustable signal is controlled by the adjustable voltage, such that it will be larger than that of the PWM signal and as a result, the number of switching the switch of the output stage is decreased, thereby reducing the switching loss and improving the efficiency of the voltage regulator.
