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.

摘要： This disclosure provides an electrical switch based on tunneling electric contacts. Electrodes of the switch are formed to have reciprocal apparent contact surfaces, each smooth such that a compressed (in contact) composite mean asperity height between these surfaces is significantly smaller than an electron tunneling length of the switch. A movement mechanism is used to physically move one or both electrodes to vary the gap between electrodes to be greater than/less than the electron tunneling length. In select embodiments, the movement mechanism is electrically actuated and is amenable to relatively high frequency operation. The nano smooth surfaces provide for a tunneling switch where current flow is not primarily dependent on contact force between electrodes, and leads to a highly conductive ON state exceeding high performance, high-contact force mechanical switches, while also being amenable to high frequency operation.

The first application commands the microcontroller to generate a first signal that is received at a first pin on a high side integrated circuit to transition a first plurality of FET switches to an open operational state, and that is received at a first pin on the low side integrated circuit to transition a second plurality of FET switches to the open operational state. The second application commands the microcontroller to generate a second signal that is received at a second pin on the high side integrated circuit to transition the first plurality of FET switches to the open operational state, and that is received at a second pin on the low side integrated circuit to transition the second plurality of FET switches to the open operational state.

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.
