  • Publication number: 20230344355
    Abstract: A power switching apparatus (P100) for a switching-mode power supply is provided. The switching apparatus (P100) comprises a power switch (M100), a switching controller (SC100), a voltage converter (Ra100) and a power capacitor (Csc100). The power switch (M100) is configured for connection with a power input device to form a power supply circuit to receive power from a power source. The switching controller (Csc100) is operable to turn on or turn off the power switch (M100). When the power switch (M100) is turned on, power is to flow from the power source into the power input device. When the power switch (M100) is turned off, power is to stop flowing from the power source into the power input device. The voltage converter (Ra100) is configured to receive power from the power source when the power switch (M100) is turned on and to output a regulated voltage.

  • Patent number: 11764098
    Abstract: When picking a die from an adhesive tape, a collet of a pick arm is positioned at a distance over the die, the die being mounted on a first surface of the adhesive tape. A flow of air is then generated onto a second surface of the adhesive surface opposite to the first surface for blowing the adhesive tape to displace the die towards a die-holding surface of the collet. Thereafter, the die is retained on the die-holding surface of the collet while the adhesive tape separates from the die.

  • Publication number: 20230253882
    Abstract: Circuits and methods for reducing lagging responses of a power converter to changes in circuit voltages or current, over-shoot/under-shoot when a target output voltage changes faster than the power converter's response, and open loop conditions. Embodiments include scanning a feedback voltage from a load powered by a voltage output by a power converter controlled by a PWM control signal; detecting an under-regulation condition; and, while the under-regulation condition is detected, increasing a clock signal rate to a counter outputting a count value usable to generate the PWM control signal. Embodiments include comparing a target output voltage to a signal representative of an output voltage of the power converter; indicating an under-shoot or over-shoot condition if the voltage difference exceeds a corresponding offset value; and limiting the range of values for an M-bit count value used to generate the PWM control signal to mitigate the under-shoot or over-shoot condition.

  • Patent number: 11723283
    Abstract: Embodiments of the present disclosure generally include spin-orbit torque magnetoresistive random-access memory (SOT-MRAM) devices and methods of manufacture thereof. The SOT-MRAM devices described herein include an SOT layer laterally aligned with a magnetic tunnel junction (MTJ) stack and formed over a trench in an interconnect. Thus, the presence of the SOT layer outside the area of the MTJ stack is eliminated, and electric current passes from the interconnect to the SOT layer by SOT-interconnect overlap. The devices and methods described herein reduce the formation of shunting current and enable the MTJ to self-align with the SOT layer in a single etching process.
