The high-side switch is connected between a high potential terminal and an output terminal. The rectifier is connected between the output terminal and a low potential terminal, and forward direction of the rectifier is the direction from the low potential terminal to the output terminal. The driver supplies a first voltage to a control terminal of the high-side switch in accordance with a high-side control signal and turns the high-side switch on. The driver supplies a second voltage being higher than the first voltage to the control terminal of the high-side switch when the voltage of the output terminal increases to not less than a predetermined value.

摘要： A current balancer suitable for a multi-phase power converting device is provided. The current balancer includes an error detection unit and a plurality of pulse control units. Each of the pulse control units includes a current-to-voltage converter, a charging and discharging controller, a capacitor, and a comparator. The error detection unit detects a plurality of channel currents generated by the multi-phase power converting device, and generates a plurality of error currents by calculating. The charging and discharging controller provides a charging voltage or a discharging voltage according to a constant pulse-width modulation (PWM) signal. When the channel currents are balanced, the comparator generates a PWM signal with a constant duty cycle. When the channel currents are not balanced, an error voltage generated by the current-to-voltage converter is used to adjust a voltage level of the charging voltage or the discharging voltage, so that the PWM signal is varied correspondingly.

During single-phase operation of the multiphase power converter, an enhanced phase control circuit and method monitor the summation of the phase currents, and when the summation becomes higher than a threshold, switch the multiphase power converter to a higher power zone to increase the number of active phases.
