摘要： A programmable after-package, on-chip reference voltage trim circuit for an integrated circuit having a plurality of programmable trim cells generating a programmed sequence. A converter is provided to convert the bit sequence into a trim current. The trim current is added to an initial value of a reference voltage to be trimmed, as generated by the integrated circuit. Once the correct value of the trim current is determined, isolation circuitry is programmed to isolate the trim circuitry from the remainder of the IC, thereby freeing the logic and package pins associated with the IC for use by users of the IC. The preferred trim circuitry includes fuses which are blown in accordance with a bit value supplied to the trim cell to permanently fix a trim current value, once a best fit value is determined.

摘要： A DC to DC controller for controlling an inrush current from a DC to DC converter to a battery system having an internal isolating switch. The DC to DC controller is configured to control the DC to DC converter based on a state of the internal isolating switch. If the switch is open, the DC to DC controller adjusts the output voltage of the DC to DC converter to a predetermined voltage level. Based on the value of such voltage level, in rush current from the DC to DC converter to the battery system can be reduced or eliminated when the isolating switch changes from an open state to a closed state. An electronic device including such a DC to DC controller is provided. Related methods for controlling inrush current are also provided.

摘要： A current mode charger controller for controlling a DC to DC converter. The current mode charger may include a first error amplifier having an output coupled to a common node. The first error amplifier may be configured to compare a first signal representative of a charging current provided to a rechargeable battery with a maximum charging current and provide a current control signal in response to the comparison. The current mode charger controller may further include an internal compensation network coupled to the common node, and a comparator configured to compare an inductor current signal representative of an inductor current through an inductor of the DC to DC converter with a compensation signal. The need for any external compensation for the current mode charger controller may be eliminated.
