  • Battery-powered current regulator for pulsed loads
    Patent number: 11191142
    Abstract: A current regulator for a pulsed load is provided herein. The current regulator may include: an input power source; a current sense circuit; a capacitive energy storage device; a current sink driver; a current source charger which receives input current from the input power source via the current sense circuit and provides a charge for the capacitive energy storage device coupled between the current source charger and the current sink driver which drives the pulsed load; a power monitor circuitry which generates a feedback signal, based on a function of the input power and a function of at least one of: voltage across the capacitive energy storage, or voltage across the current sink driver; and a pulse width modulation (PWM) or pulse frequency modulation (PFM) circuitry which controls the current source charger based on the feedback signal.
