  • Publication number: 20240356443
    Abstract: A time based boost DC-DC converter generates an output voltage using an inductor. A voltage error between the output voltage and a reference voltage is determined and processed in a) an integral control branch which converts the voltage error into an integral control current signal used to control a current controlled oscillator, and b) a proportional branch which converts the voltage error into a proportional control current signal used to control signal a delay line. Current flowing in the inductor is sensed, attenuated and used to apply adjustment to the integral and proportional control current signals. The output from the current controlled oscillator is passed through the delay line and phase detected in order to generate pulse width modulation (PWM) control signaling driving switch operation in the converter.

  • Patent number: 12125803
    Abstract: A leadframe has a die pad area and an outer layer of a first metal having a first oxidation potential. The leadframe is placed in contact with a solution containing a second metal having a second oxidation potential, the second oxidation potential being more negative than the first oxidation potential. Radiation energy is then applied to the die pad area of the leadframe contacted with the solution to cause a local increase in temperature of the leadframe. As a result of the temperature increase, a layer of said second metal is selectively provided at the die pad area of the leadframe by a galvanic displacement reaction. An oxidation of the outer layer of the leadframe is then performed to provide an enhancing layer which counters device package delamination.
