摘要： A protection circuit includes a voltage conversion unit, a voltage clamping unit, and a power supply. The voltage conversion unit converts a first voltage from the power supply into a second voltage and outputs the second voltage to an electronic element. The voltage clamping unit stops the power supply from operating if the second voltage is greater than a rated voltage of the electronic element.

摘要： A buck switching regulator includes: a power stage, which includes: an upper-gate switch, a lower-gate switch and an inductor, connected with one another at a switching node; and a supply control switch, controlling the power supply form an output terminal to a load. An overvoltage protection method includes the following steps: (A) sensing a voltage of the switching node, to obtain a switching node voltage; (B) determining whether an overvoltage event occurs in the switching node voltage; and (C) if it is determined yes in the step (B), outputting a protection signal. An overvoltage event is determined directly according to the switching node voltage, not directly according to the output voltage.

摘要： Even when an overvoltage suppression circuit is not formed due to failure of an overvoltage suppression switch, overvoltage application to semiconductors and a filter capacitor is prevented. A control unit controls the overvoltage suppression circuit to short-circuit the filter capacitor when the voltage thereacross exceeds a predetermined value. Then when non-operation of the overvoltage suppression circuit is detected, the control unit opens an AC breaker and AC switch, and closes a charging switch. Thereafter, the control unit turns ON the converter element (or converter element) connecting to the filter capacitor terminal (or terminal) and a charging resistor, and turns ON converter element (or converter element) connecting to terminal (or terminal) of filter capacitor and connecting to the terminal of the transformer not connected to charging resistor.

摘要： A circuit to supply power to a detachable load incorporates a power source, a power converter and an array of capacitors. Upon connection of the detachable load, the capacitors of the array of capacitors are automatically configured into a desired series, parallel or combination series and parallel configuration of interconnections to accommodate limitations in the voltage ranges of the capacitors in being coupled to the load and/or to achieve other desired characteristics of electrical power to be provided to the load. Further, upon connection of the detachable load, a limit on current flow imposed by the power converter may be set to a desired level to achieve desired characteristics of electrical power to be provided to the load and/or desired characteristics of charging and discharging behaviors of the array of capacitors.

摘要： An inductor 6 accumulates an energy therein or releases the accumulated energy according to the state of a main switch element 10 being turned ON/OFF. When the inductor 6 releases an energy, if a sub-switch element 12 is in the ON state, a current is passed through a circuit downstream of the sub-switch element 12, thereby increasing an output voltage VO1. The sub-switch element 12 is a P-channel MOS transistor, and a sub-switch control circuit 18 outputs a control signal VCT1 for the sub-switch element 12. A level shift circuit 19 receives an output-side potential VP of the inductor 6, and outputs, as a control signal VG1 applied to the gate of the sub-switch element 12, the potential VP if the control signal VCT1 is at the L level or a potential (VP-VM) lower than the potential VP if the control signal VCT1 is at the H level. Thus, the output voltage of the DC-DC converter can be made precisely equal to the target voltage.

摘要： A voltage regulator is disclosed for regulating the voltage supplied by an energy source such as a photovoltaic array. The regulator includes a thermally activated switch which is coupled in series between the regulator input and output. A control circuit monitors the voltage supplied to a load and generates a control signal which is responsive to the measured to the load voltage. A heater, responsive to the control voltage, is positioned near the thermally activated switch and causes the switch to open when the sensed voltage rises above a prescribed limit. Hysteresis in the voltage regulator is provided by thermal insulation which retards the dissipation of heat from the vicinity of the switch causing the switch to remain open.

摘要： According to one embodiment, a memory system connectable to a host includes a nonvolatile memory, a controller, and a power control circuit. The controller controls the nonvolatile memory. The power control circuit controls power to be supplied to the controller and the nonvolatile memory and includes one or more DC/DC converters. The nonvolatile memory and the controller include one or more circuit blocks. Each of the one or more DC/DC converters supplies an internal power supply voltage to one of the one or more circuit blocks. A first DC/DC converter of the one or more DC/DC converters transitions to a forced pulse width modulation mode in response to the memory system that has transitioned from a low power consumption mode to a normal operation mode.
