  • Patent number: 11664648
    Abstract: Embodiments of the disclosure include a switch having an on-state resistance that varies based on a temperature coefficient of the switch and an overcurrent protection circuit coupled to the switch and having an adjustable overcurrent threshold level determined based on an adjustable voltage generated by the overcurrent protection circuit, the adjustable voltage generated based on the temperature coefficient of the switch.

  • Patent number: 11664732
    Abstract: This present invention is an invented synchronous clock generator for the multiphase DC-DC converter system, comprising a front-end buffer circuit, a ramp signal generator circuit, a configurable equally divided reference voltage generator circuit, a set of comparators, a 10-ns pulse generator, multiple 30-ns pulse generators, and a pulse combination circuit. The synchronous clock generator can produce a clock pulse signal SYNC at N (total phase number) times the single-phase switching frequency. Within one synchronous loop period, a 10-ns pulse is first generated and followed by N-1 30-ns pulses. The master power stage chip detects the 10-ns pulse, and all the slave power stages detect and count the 30-ns pulses to determine when to set their output signal PWM. Thus, the invention can produce the new SYNC signal immediately with balanced phase shift while allowing the changing of the total phase number N by the total phase number register.
