    摘要: A method for balancing in a multi-phase DC-DC converter, wherein at least two cells are provided, in each of which at least two phases of the DC-DC converter are grouped, wherein an operation of the individual cells is correlated with respective cell operating values, and an operation of the individual phases is correlated with respective phase operating values, and for balancing, an at least two-stage regulation is carried out with the steps: modulating the phase operating values of the phases as per a first regulation so that the phase operating values are modulated within the cell, and/or modulating the cell operating values of the cells as per a second regulation such that the cell operating values are modulated among themselves.

    摘要: This invention relates to the field of vibration switches, and more particularly to vibration switches used for DC to DC switching conversion. DC to DC convertors use an electrical switch like MOSFET/transistor for conversion to switched DC. The MOSFET/transistor requires a power source for the switching action. A vibration switch comprising of metal or conductive polymer strip can be used for the switching action in a DC to DC convertor. The strip is bent by using a small weight attached to one end. When exposed to vibration beyond a certain threshold the metal strip oscillates and performs multiple switching operations by connecting to the contact terminal. The switched DC thus produced could be filtered to generate a DC output. This switch does not require power for operation. The vibration sensitivity and frequency of oscillations of the switch can be controlled using the hardness of the material used.

    摘要: The present invention discloses a voltage conversion circuit having self-adaptive mechanism. A control branch includes a first resistor coupled between a second power supply and a control terminal, and a switch circuit that is coupled between the control terminal and a ground terminal and receives an input voltage from an input terminal to generate a control voltage at the control terminal. A voltage-withstanding P-type transistor circuit of an output branch is coupled between the second power supply and the output terminal that generates an output voltage and is controlled by the control voltage. A voltage-withstanding N-type transistor circuit of the output branch is coupled between the output terminal and the ground terminal and is controlled by an inverted input voltage. When the input voltage is at a first power domain high/low state, the output voltage is at a second power domain high/low state.

    摘要: A Charge Pump Buck Converter (CPBC) includes a BC including an inductor and a CP coupled in parallel. Control logic is coupled to a switch driver coupled to a power switch(es). Control circuitry includes a voltage sensor sensing Vout and a voltage level generator for generating a first voltage level coupled to the CP stage and a second voltage level coupled to a duty cycle/rate generator block providing an input to an under voltage (UV) monitor coupled between OUT and the control logic. The control circuitry disables the CP when Vout>a first Vout level and controls the BC to regulate to a second Vout level>the first Vout level. During handoff between CP and BC during power up if Vout drops below a UV threshold, the UV monitor block modifies an input applied to the control logic for increasing charging supplied to the inductor.

The fully mechanical micromachined oscillator and mechanism are driven using only a DC power source on at least one substrate such as a semiconductor chip. The oscillator and mechanism preferably include an electrothermal actuator, that, when actuated, opens a switch to cut off supply current to the actuator. Two versions of the oscillator and mechanism are provided using distinct hysteresis mechanisms, one structural and the other thermal.
